DISQUS

TouchJSON is used in Places, a location-based restaurant, coffee shop, and nightlife finder.

Facebook is a place where people come to play. Its all about entertainment people. Would you open up a word processing kiosk in a bar with all your friends? Om obviously doesn't understand the platform. Productivity apps probably can have a niche on LinkedIn, but not on Facebook.

The difference between text micro-blogging and video micro-blogging is that text can be scanned easily and processed very fast. That is why Twitter works. Voice and video require playing each one individually. You can't scan ahead and process it quickly.

I don' think having a centralized place to distribute apps is a bad idea. It works on Facebook. It makes lives easier for developers, and puts everyone on a level playing field. Apps will be judged by reviews in the AppStore, so it won't necessarily be based on the advertising budget of a company with the funds.

I have already built one app on the platform and can't wait for the store to launch.

The future will be a combination of distributed services like OpenID and OAuth, and services like FriendFeed. This won't happen overnight though.

Just wanted to mention that in the latest Rails trunk, you have to prefix a nested resource with its parent. So ingredient_path(@recipe, @ingredient) will become recipe_ingredient_path(@recipe, @ingredient).
