Really hate to tell you guys, but we have some very weird production issues and they turned off our activities stream for applications.

It is really not clear if we are causing the current production issues. I'm on it (together with some other really smart people).

As before, you can still call the REST api calls directly to retrieve your own feed for your application. I'm not aware of any application yet who is doing this in production.

Update 2-7-2009: We are all back to normal (except for FF3. A fix for this will roll into production in 2 weeks)
