Yes, since the recent site update all projects have vanished and I also see that diaries still appear on recentlog after a user account has been marked as spam and deleted (see e.g. phpgurru's diary entry below - not 100% certain phpgurru was a spammer btw, people might have been a bit triggerhappy there!)
As ncm mentioned, multithreading in C++ seems to be going in the right direction, though I've not had time to follow it in the last 2-3 months. There are also very cool things like variadic templates coming. I hope I'll be contributing to libstdc++ again before all the interesting new work is done!
