some people are better at answering questions on side games
I don't understand your reason. If people are better at answering certain questions, they can carry on answering those questions. There is no need for a separate section.
The RMT was moved to a separate section partly because there were a lot of them in the question lists, but also partly because they are a different format of question, like Meta is.
By the way, if you 'favorite' some tags, questions on those tags should appear in your updates page: http://pokemondb.net/pokebase/updates
