I edit Wikipedia fairly regularly, and have never had anything reverted.

Actually, there was one time when I edited John Dvorak's page to call him a "gasbag". That was reverted pretty quickly, but he did mention the incident on his podcast (which was the point of making the edit). (Also, he is a gas bag. Thankfully I haven't heard about him for a few years now ;)

But really, no legitimate edits of mine have been reverted :)
