I noticed that c++11 tag is a synonym of c++0x so will be renamed to c++0x. c++0x name is quite outdated and will be never correct anymore. It's already 2011. Most probably the new standard will be approved this autumn. So rename it to an older name if c++11 will be the correct one (with high probability)?
Edit: it seems these two have been disconnected now. There are 33 c++11 questions and 1549 c++0x questions. c++0x has been proposed as a synonym for c++11 but nobody has voted for it, and probably nobody can because they don't have tag rep in c++11. Sigh.
