The topic of self-answering questions immediately is a complex one. On one hand we do not want to fill up the site with low-quality material by people hungry for raising their reputation. On the other hand, new users have a disadvantage because people have reduced their upvoting frequency (not me! I'm a site leader in overall upvotes; everyone else please keep voting with the same frequency as you did at the start, so that it's fair for the new users!), and we want users to participate, and we also want to have more material on the site that's searchable and attracts more users to visit.
If a user just asks how to do something in their favorite software, and immediately answers with how to do it, perhaps we want to consider whether or not that question is really something challenging, or if it's just regurgitating what someone already knows how to do. If a user is immediately self-answering easy questions of their own more than say, once every 6 months, I'm tempted to consider converting the question and answer to Community Wiki so the user doesn't get points (if the user is doing this to provide more searchable content on the site, then they'll be okay with this; and if they are doing this to gain quick reputation, then it's questionable whether we want to allow it). However Tristan Maxson suggested that we make just the answer a community wiki. Maybe that's a better idea. Even then, we run the risk of allowing a lot of low-quality content to fill up the site, and users will get a lot of upvotes for a question that might not actually be great, but it seems like a fair middle ground (for now) between making both the question and answer Community Wiki, and allowing the users to "run wild" with immediate self-answering for personal reputation gain. Shall we implement Tristan's suggestion? I'm in favor of it as a temporary measure for now, until we've had more time to think about it and to see the results of how this works out.
