why do some tags have links and others don't (not even a local search)?

also annoying is that there are so many posts that don't have a comment field.

If I post something I have to accept the possibility that someone might comment on it.
not allowing comments would be silly, because if they can't comment there they might do it somewhere else, and I might not see that comment!

don't get me wrong though, in my opinion its still the best platform of its class
