What changes? We have two more mods that are kind of active (HopelessN00b and me), but that's about all of the changes I see. 

To your points: 

> There is much more migration. I thank for you all of this, I never understood why is the migration handled as taboo, especially if it could save a question.

The best way to deal with a crap question is to get rid of it. Forcing it on another site is unfair to that sites' users and I don't want to migrate crap. Also, I don't have the impression that we migrated more questions than before, but if you like you can dig into the data tools to get some nice statistics. 

> Moderators (especially @MichaelHampton and our new @Sven) are like to particip in close/open votes directly.

Yes. If I see a question that is clearly off topic, I'll close it. I also close potential topical question that need massive edits and reopen them if I see them in the respective review queue and they are actually improved (which happens far too seldom). I also *don't* VtC on a large amount of questions because my vote is binding. Your idea of using a second account is completely unrealistic, and there will likely never be a  non-binding vote for mods as Atwood decided we don't need this feature, but even if we had it, you would see about the same amount of mod votes from me as now, plus even more non-mod votes. 

Also, you have always the option to vote for a reopen. If you do this, the question will be placed in the reopen review queue where enough users will see it to override a mod decision if they deem it necessary. 

> Closed questions are often nearly instantly deleted. I think, it is bad.

I don't see this. Real bad questions tend to collect three close votes fast, but we don't want these anyway and this is a small percentage of question. "Normal" closed questions without answers will be autodeleted by the system after some time, which is also a good thing in my view. Other than that, there is no significant manual deletion going on. 

Howerver, I would like to delete much more stuff much earlier to keep our site nice and clean - having a start page with lots of closed and downvoted questions is not very inviting to potential high value users we would like to attract. That wouldn't be an issue if we had filters for what we get to see, but this isn't the case.
