> Blocking professionals who have the solution because they don't have 100 points is a real issue.
Like I said in another reply, I'm not saying block, just filter by default. Though, perhaps a time limited block would be useful, and solve another problem: experienced users know how to answer quickly, and often do so before new users get the chance to provide one.
Most questions don't get answers. The problem is not users giving excellent, well thought out answers so quickly a new user cannot find something to answer. There are 3M questions without any answer. There are lots of opportunities to provide answers. Most people, however dontnknownhow to write a good question... or for that matter, a good answer.
Look at the newest questions, or triage, or help and improvement queues. There are many more questions than there are answers.
