For several recent years, the contents of questions on CSTheory.SE are strict subsets of those here on CS.SE
Especially, theoretical questions here and there are often linked to each other. Also, many have asked a question on both sites. Then moderator actions like close, merge, migrate have to be taken. Very much work to do in between just 2 sites.
Maybe more importantly, practical questions here on CS.SE are rarely allowed on CSTheory.SE
So, why do we need to maintain a tiny site like CSTheory.SE while everything would be simpler and cleaner by merging it to this site CS.SE?
Personally, I hope for a happy merging event in far future.
Sorry if this question annoys CSTheory.SE site's moderators.
