There is actually a place for things like that, but it hasn't been
updated for years, so it's woefully out of date:

http://www.boost.org/community/cpp.html

I'm really not sure what to do with it. No seems keen to do this kind
thing, and http://isocpp.org/ is tracking C++ development articles, so
it might be redundant now anyway.
