Definitely: I stopped contributing (content and money) to Wikipedia after non-notable deletions ~2006 took out most of my contributions. At the time it was noted that it was easier to list a porn star (anything with a major distributor was automatically considered notable) than an academic who hadn't managed to get a real dead-tree newspaper article written about them (journals, awards, etc. didn't count as much as 2 paragraphs in USA Today). I hope that's changed since then but it definitely killed any interest I had in contributing more time for a uninterested editor to discard without comment.
