Something does not compute there. If your changes are getting reverted, obviously someone cares enough to notice, so it follows that they should care enough to check the discussion. Are you sure you're not just getting hit by a bot? Maybe you did not tag your changes properly? If anything, there might be a problem that the admins should look at. I would like to see some of these changes you are talking about.
My experience with Wikipedia has been hit or miss. Sometimes I'll find an older article and fix it up a bit and it will stay. Other times I get my edit reverted by an over zealous neck beard who can't handle being wrong on the internet. I don't have the time to battle these types of people. This is what sunk, "Wikipedia is not a creditable source" into my brain.
