For a long time, the aboutabout page described Stack Exchange as drawing from wikis, share-and-vote sites, blogs and forums. “How do I fix this program?” is best suited for forums. Wikis need a structure, so that you can find the right page. A debugging service works differently: there's no good indexing schemes for buggy programs. Share-and-vote is secondary: a debugging service requires content to be provided in the form of solutions to make the program work. Blogs are inadapted because they're completely focused on the initial content, whereas the most important part of a debugging service is the solutions.
Now this kind of modeling is common enough in the daily life of a programmer that I think it can fit under “software algorithms”“software algorithms”. But I admit that it is marginal. For this reason, I have so far refrained from voting to reopen the question.
