Speaking as a user on cstheory.SE: yes, please! Finally there is a way to treat good but low-level questions properly, we should use it. Several of the high-rep users here are also active on cs.SE so we have both implicit (we are all (?) computer scientists) and explicit expertise regarding the scope of cs.SE.
Speaking as a mod on cs.SE: Sure, keep them coming -- as long as the questions are good! I trust the cstheory community to know and respect our scope. So far, cs.SE has clearly profited from the migrations. I assume the volume will drop once cs.SE becomes more visible and more known in the SE community.
cstheory -> cs is probably the most natural migration path there is in the current SE network. In the future, cs -> cstheory will be used, too; we have had several theory questions which have remained unanswered. More on that later.
Update: As a mod on cs.SE, I'm still in favor of this migration path. We have enough community moderation in place by now to effectively and efficiently deal with cases of accidental crap migration.
