I joined the StackExchange network approximately 3 months ago, specifically to help contribute answers and moderation to the StackOverflow site. In the short-time that I've been a member, I have to say that I have seen far too many users with a low-to-zero Acceptance Rate.
While gaining reputation is an important factor for the website and motivates most to answer, helping others solve their problems and providing information for future visitors is the true purpose. This statement has two points:
- The motivation to force-suggest a user to accept an answer is driven by the desire of reputation, not to help future visitors.
- The goal to help future visitors is to force-suggest a user to accept an answer.
I, personally, am all-for having a notification displayed to an individual to suggest that they should accept an answer to some or all of their questions. Providing them with links to the documentation/articles that give information on how to accept an answer and/or why it should be done would be very beneficial as well (there's a good chance that the user just doesn't know).
You have not accepted an answer to any of your questions. Consider
accepting an answer if it has solved your problem.
As the network is designed to be helpful to the community, I don't think that denying users the privilege to ask new questions if they have a low/zero acceptance score is very beneficial. I have seen numerous comment-barrages similar to "0% accept rate? no thanks" or "would like to help, but acceptance score too low" and I just don't think that these are beneficial to anyone but rep-greedy members.
In response to a comment, I think that the ability for other members to see someone's acceptance score should actually be a reputation-privilege that should be earned - and I think that it should come at the 20k level. If a user has been contributing to the website enough to reach the 20k rep level, I feel that they would/should be responsible enough to offer a helpful suggestion to an asker to improve their acceptance rate and would also help answer a question without worrying about not receiving their +15.
