Someone would have to set up the subject structure under
D.Learn. Then a
possibly required input field (thinking web interface) could
specify the
subject the question belongs to. A voting system would then
sort the
responses after relevance and usefulness. It would help
building useful,
easy accessible and comprehensive documentation.
Also, language and library debates could be tagged by subject
and the
posts could be rated by votes in order to organize and extract
key
points out of long threads.
....So basically Stack Exchange.
Why not simply point people to stackoverflow tag [d]?
Since this is the D site and lots of useful information is
exchanged here and expected to be found here.
The infrastructure is already in place for pretty much exactly
what you are talking about, and several of the people here have
accounts there.
