I'm not referring to an overall karma score, but to each individual post. Posts at -1 are much less credible to readers than posts which aren't at negative values. And unlike one's overall karma score, the -1 is right there where everyone can easily see it and react.
So it's not your reputation that gets destroyed but the credibility of your posts? I still don't see it. Maybe I'm a unique snowflake, but I treat comment karma as the attitude of the hivemind with a lot of noise added, so a comment at -1 means to me that 1 (one, single, solo) person disliked it. So what? A comment universally liked is probably too bland and restates the obvious, anyway.
Richard Kennaway has posted about an edit war on the wiki. Richard, thank you.
Unfortunately, I've only used the wiki a little, and don't have a feeling for why the edit history for an article is inaccessible. Is the wiki broken or has someone found a way to hack it? Let it be known that hacking the wiki is something I'll ban for.
VoiceofRa, I'd like to know why you deleted Gleb's article. Presumably you have some reason for why you think it was unsatisfactory.
I'm also notifying tech in the hope of finding out what happened to the edit history.
