Looking through the messages on this list, it was quickly pointed out that our press release had one fact wrong, I started The Wikipedia Signpost in 2005, not 2006. The announcement was drafted and issued in a very short time (we went directly from the meeting where we elected officers to the press conference), so there wasn't much opportunity for proofreading. But nobody should blame Jay for this error anyway - he asked me when I had created the Signpost, and not being online to look it up, I attempted to calculate backward from memory. I got it wrong, which I realized not long afterward, but by then the press release had already gone out.
It's an interesting illustration of the challenges in verifying information, and how collaboration can be useful. Erroneous statements, whether in a news story or a Wikipedia article, often happen because the writer thought he knew something, but his understanding was flawed or his memory of it inadequate. This applies even to people who specialize in that area, who ought to be well placed to know such things. For example, you would think that I'd be just about the best person possible to ask when I started the Signpost. As it turns out, you're even better off asking people who read it and know where to look up the answer.
This is still something we need to work on, though. I think we're decent at quick copy-editing, less strong at fact-checking. Sometimes we manage to at least identify what needs to be checked - [citation needed] - but there's still a whole lot of checking out there to be done.
