Yes, people change answers on WikiAnswers all of the time. It is to better the quality of the answer. So, yes, it is completely true.
Yes, they can be found all around the site.
I do not use Answerbag in addition to WikiAnswers. Answerbag is much like Yahoo! Answers, and has the same quality flaws as Yahoo! Answers. The answers are as-is, while WikiAnswers has an answer being worked on by hundreds of contributors until the answer is perfect.
The Answers platform is wiki based - any user can ask, answer, edit or vote on the quality of an answer.
Answers are vetted by Supervisors. They go onto a special page which has all the recent answers so they can approve the answers and catch out vandalism. They can also mark quality by deciding whether an answer is acceptable, good or excellent.
WikiAnswers, actually, is more popular. Recently, WikiAnswers has surpassed Yahoo! in visitors (WikiAnswers was already superior quality wise).View the related link below, and view the second graph in the related link to see why WikiAnswers is more popular.

WikiAnswers is a website in progress still, as many questions are asked but a third or less get answered. WikiAnswers thrives on contributors to answer questions and make the site better. These volunteer contributors put hundreds of hours in for WikiAnswers to answer questions to improve the overall quality of the site. If you know the answer to a question, answer it. The answers do not automatically pop up here and appear from thin air - they have to get here some how. This answer misses the point. Or at least many of us cannot find tne answers. Questions that have answers do not show the answers. Why not?
Yes, corrections are made to questions and answers when a supervisor, contributor, SPA etc., finds something that is incorrectly spelled. Everyone does their best to contribute and help make the quality of WikiAnswers better.
