Other than the crowd of games people, you’d be surprised by what Web 2.0 folks are speaking:
- Gaia Online, which started out as a bunch of online forums
- HotOrNot, which has virtual goods in the form of roses that you can give
- RockYou, a recent high-flying widget company
- Kongregate, a self-described "YouTube for games"
- Dogster, a pets social-networking site with virtual gifts
- LiveJournal, which has "v-gifts" that users can give each other
And of course, check out the list of attendees for a colorful bunch.
Autodesk? Motorola? eBay? And a whole ton of VCs?
You can definitely tell this space is heating up :) Perhaps people will start looking at this as a serious alternative or compliment to the ad-centric model that exists today.
