See table of contents for full list of web 2.0 expo posts

Opening Remarks Brady Forrest (O’Reilly Media, Inc.), Sarah Milstein (TechWeb)

The Online Animal Economy: Examining the Cute Kitty Video Patrick Davison (WhatWeKnowSoFar/MemeFactory)

  • Talking about cats. How could this be bad? The title of this talk is one chapter in a book the author is writing and the talk is about the author went about writing it.
  • The videos got laughter unsurprisingly. It isn’t just kittys. I liked the dog riding a turtle.
  • The theory is this is about human-animal interaction being funny being more public/tv and cute being more private/youtube. Theory was wrong. Most youtube videos were exotic animals, violent animals, funny, cute and sexual. Kitties dominate the cute category. Including baby panda as a kitty. New media gets wisdom and weird stuff from crowd.

The Five Laws of Engagement Siobhan Quinn (foursquare)

  1. We seek comfort in relationships, surrounds us with a community – anonymous communities still count (like postsecret where anonymously submit secret via postcard)
  2. We are all unique and have something to say; give us tools to express ourselves – blog, comments
  3. We need to feel important, use rewards to make us feel special – use exclusivity to do so (like invite mechanism for gmail invites) or competition or reputation
  4. We are hypnotized by beauty, give us something pretty to look at
  5. We are captivated by the unknown, captivate curiousity -a monkey will try to solve a puzzle just because it is there – use surprise (different prize for different checkins) or organization (visual chaos) or teasing (7 habits book has teaser in title)

Las Vegas represents these 5 laws in a physical place. The reason people feel bad after is the 5 laws exploit us rather than using to make better people/community. Reward people or inspire them.
Note: Four Square launched feature today with ios 5 location feature so can push info about places pass by. [I don’t use four square for privacy reasons, new feature sounds like another level of creepyness]

CMO = chief marketing officer
IBM did a study and learned:

  • Expecting more complexity over time
  • Think need to focus on delivering vslue to empowered customers, foster lasting connections and capture value/measure results

Talk was somewhat dry, but if you want to read the study: www.ibm.com/cmostudt

Sex, Lies, and Data Mining R. Luke DuBois (Polytechnic Institute of NYU)

  • Speaker uses data to make portraits. Data changing too fast, getting dizzy.
  • See eye charts with words presidents used at lukedubois.com – same idea as tag clouds
  • Registered on 21 dating sites in every zip code to gather data on profiled. Then overlaid key traits on map of US. NYC # 1 word is “now”. By contrast to most cities which have a noun.
  • See online at perfect.lukedubois.com
  • People have more confidence in online info than info from a sales clerk
  • Now you can borrow an item to where once
  • There are a lot of fashion tyoe websites out there. Similarly for using platforms like youtube for fashion
  • While computation power is increasing, human attention capacity is about the same or decreasing.
  • A computer is mostky i/o and less cpu/memory parts
  • Instead of cheap laptops, we have more types of devices with chips -phones, tablets, car security remote, credit cards, etc
  • Competition drives diverification because add different features
  • Mouse and keyboard succesful for human scale device. Similarly, touch best for small devices. [not for typing on an ipad]
  • Motion remotes good for large screens
  • Productivity mostly happens on human scale devices and others are for consumption
  • Mouse and keyboard not going away; just becoming smaller portion of devices. True for other i/o devices even brain based input. The myth is one i/o device for everything.
  • Currently in era of specialization.

I really liked this keynote!

VC Perspective Joanne Wilson, Mo Koyfman (Spark Capital)

This one is more about the next thing – startup showcase than a keynote. The judges of that eben are covering how they will judge startups before people leave. Like that one of them commented the couch isn’t on the stage.

Live blogging web 2.0 expo – web performance anti patterns and listening to your customers

See table of contents for full list of web 2.0 expo posts

I think the performance anti patterns one will be more interesting, but Microsoft does have good points about your customers being important and basics for most websites. And Hotnail has changed a lot over time.

Microsoft and Hotmail

  • Hotmail was one of the first webmails but is now largely popular only outside the US.
  • Gmail did well – big inbox, text ads, smooth interface,short release cycles
  • Recognized Microsoft asked users to pay for new features
  • If people don’t use something, it is an invention, not an innovation
  • I like that he identifies “real spam” vs newsletters that you subscribed to (and can presumably unsubscribe from)
  • The things Hotmail recognized must change are now things that one must have to do email – virtually unlimited storage, must filter spam out of inbox, performance, pre-cache content, mobile
  • ok. I know i said i wasn’t going to advertise hotmail, but the “sweep” feature makes setting up a filter less steps. Gmail: please copy. Except just the part about less steps to create a filter, not the part about having to schedule.
  • Encouraging ignoring all messages from a user vs unsubscribe. One day people are going to forget what unsubscribing means while all this bandwidth gets wasted and newsletter providers get labeled spammers
  • can create email alias for temporary person. Unlike gmail, can’t derive real email from alias.
  • “it might be cool, but i am fine where i am”. Lesson: once your customers leave, it is hard to get them bacK

How to make your website slow by Yottaa

  • Lots of requests to dowhload assets – really granular css, javascript, images. Can get yottaa score at yottaa.com to see how bad your site is in this space (coderanch did well with 95/100)
  • Fat resources – comments and whitespace in html, css, javascript (should use gzip compression), use larger images than needed (shouldn’t compress image in browser)
  • Bad server side -poor code, bad database design, inusufficient memory or slow hard drive, sharing server with others (gives unpredictable cpu use)
  • Randomness – things are fine for everyone except a few people. It only takes one resource to slow things down. This is why twitter widgets can be the bottleneck on page speed.
  • Do not use caching – set cache control properly. Both for repeat visitors and so subsequent pages in site share assets already downloaded
  • 3rd party plugins – not loading twitter, facebook, etc asynronously slows things down. A little for most users. 30-120 seconds in China because must wait for request to time out.
  • Redirect from www to other domain on the client side (use 302 not 301)
  • Add requests to resources that do not exist (404) – takes longer to return resource that does not exist than resource that does exist because looks in multiple places
  • Run javascript code while page loading
