I see that there are currently very poor questions by many new users who are not responsive to comments and downvotes by few experienced community members. This imbalance leads, in my view, to a decline in the quality of the questions and answers. For me, the question is whether this leads to more serious participation in this community or less. I don't know SE German Language very well yet to decide that. On the other hand, I wonder whether there are enough people in general to deal with the "entrance control" of the first questions.
Or to put it more simply: if there are only 3 people there, there will be no 5 close votes.
Wouldn't it then be better to switch to a threshold of 3 close votes?
