I am a frequent editor. I tend to make grammatical/spelling corrections as well as corrections on biased or subjective materials. It is my philosophy that it is up to the reader to read an article and then decide for themselves, as far as subjective materials go.
At the time of this writing, I have 1,230 edits (obviously, some better than others) at Wikipedia (see my page), so I'm pretty well established.
Hopefully I do not step on someone's toes. I know a lot of people are touchy about edits, but just understand that when anyone decides to open a wiki, it is for everyone. Not even the owner should Lord of the Manor, so to speak, because again, a wiki is for everyone.
