These are my snippets from the sessions about developing Social Networking apps and widgets.
Rock You – Jia Shen, CTO
FB Young, and women
Newsfeeds, Notifications, Invites – most important marketing elements
Which channel does it fit in? (Rummble is probably in Content or Self Expression – clarifying this might increase our conversion rate and usage)
What are the call to actions?
Do users like it? (break viral barrier)
Tune growth (install vs uninstall)
Viral multiplier – 1users causes atleast 1 other install
Tune – track everything. Rock You built a tracking system that tracks all input and output. Track spam blocking of notifications – work out what works.
Non-user pages are now more important; better contact as people check app before install
Do not miss this opportunity – HUGE audience
Promiscuity factor – different audience
Myspace, Orkut, Hi5 – will all be there at launch in March
Practise agile development – APIs are changing almost daily. Built quick, role out quick.
R. Tyler Balance @ Slide
Utilise the things available – FBML, Mock AJAX, FQL, Mobile, etc.
Widgets are not applications
Kevin Marks @ Google
Stop planning, start developing on 0.7
Hi5 and Myspace will be active within a month
If you’re an application provider, get writing
If you’re a social site, implement Shindig/Opensocial
