The long and short of it is that you really shouldn't remove a page's history unless you have a valid reason for it. What exactly a valid reason is depends on your wiki - but it could be reverted vandalism that's somehow obscene and you don't want people to see it, or a user's personal information. I'd advise you err on the side of caution for this. Note that if you remove a revision from the history and the text added in that revision is still in the page, you are breaking the terms of the license of your wiki, all contributers diserve to get recognition for their work - and this is done with the history. That's why I strongly recommend you don't use Dimension10's method, as he points out - it's only if you're the only non-spam contributor.

Penguin Pal's method is good for removing some of those valid reasons, i.e. reverted vandalism or reverted personal information.
