WordPress disappear from Opens Apps in Yahoo Mail

It is only this morning that I noticed WordPress is no longer available from Open Apps section in Yahoo Mail when I tried to open it to make some demo to one of my friends. This is how it looks like last January.

Not a big deal though, as it is still available via My Yahoo! Just feel a little bit disappointed because it is no longer there. When Open Apps is opened to public in January 2009, it does look promising, at least to me. The idea to let you do everything from within Yahoo Mail is cool idea, but the end result is far from satisfying.
Only few applications were introduced in the span of 6 months, which is not acceptable. There are 9 applications in Yahoo Mail, while My Yahoo has better number, with 24 applications. Numbers of app and app type tend to be the factor that influence users to use any ecosystem. The obvious example is how super successful iPhone App Store is with tens of thousands applications.
Taking numbers as the benchmark here, Open Apps certainly has failed to impress users.
