If you feel strongly about this subject, you probably want to follow this proposal on Meta Stack Overflow: <s>[Should we require minimum reputation to continue asking questions?][1]</s>

<s>In a nutshell: **After your first 10 questions, it will require 100 more reputation to ask every additional 10 questions.** This would also be applied retroactively, so users can be disassociated from their older questions if they didn't get many upvotes. You would need to get 2 upvotes or more on average per question to keep on going without getting rep in other ways.</s>

**Update:**

> We are reevaluating this based on community feedback. The new heuristic to prevent questions being asked will probably be based on a combination of question closes, question deletes, question flags, and lack of significant upvoting, even at very low levels (0.20 etc) -- scoped to new-ish users.

One new change is that you can [only ask 50 questions per 30 days][2]. This was initially 70 questions but quickly lowered to 50, and will probably be tweaked in the future.
