Yet Another Open Source Discovery/Directory Site: OStatic
The more the merrier: OStatic is the latest directory service for listing available Open Source packages that I have encountered so far. I haven't had much time to dig in deeper to see if it offers anything substantially more interesting than SourceKibitzer or Ohloh. But it's good to have little bit of friendly competition.
One common denominator between these sites seems to be that if I am not mistaken, they have all been bootstrapped using a set of high-profile open source "incubators": at least Codehaus, given that Woodstox and StaxMate are included from beginning (or maybe just because they are such sterling open source libs? :-) )
