The Steve Pavlina article had a discussion page which has been erased for some reason. It seems that there are people in admin positions of Wikipedia who have personal reasons for banning the article. Otherwise I don't understand why they'd erase even the discussion page, where some people were questioning why the main article has been deleted.
If you dig a little you can find
this page. It's the only page that gives a reason for banning the article. There was a vote in March of 2006 where it was decided that Steve's site isn't popular enough (doesn't get enough traffic) to warrant a Wikipedia entry. Traffic has increased a lot since then though but the article remains locked. I guess we have to try contacting the admins.
