As proof that the first meeting was at the Tech Shop one of the editors cited a Wired article where the author mentioned they attended a meeting there in Menlo Park. We absolutely held meetings there and I am forever grateful to Jim Newton for sponsoring us. Nowhere in the article (I believe by Robert Strohmeyer) did it mention this was the first meeting. And actually... I'm re-reading it... it talks about meeting at a law firm in Palo Alto, which I think was where we had our second and third meetings, so the conversation about the Tech Shop meetings being the first meeting is even weirder.
Anyway... no amount of discussion could convince the volunteer wikipedia editor that our first meeting was at the GooglePlex, even the post on Boing Boing announcing it (thank you Cory Doctorow for amplifying the message.) They just decided they were right and I was wrong.
In the end they nominated the article for deletion and by that time I was totally okay with it. The club had dissolved after the release of Android and the iPhone, where you could actually write your own phone apps. And now with the Pine Phone (and other platforms I can't remember the name of) it's not clear what the club would be advocating for.
Anyway, I still think the Wikipedia is a great place to go find references about a subject you're not familiar with. But you absolutely need to do due diligence and continue finding references if your search is important.
And to be clear... my point is... sometimes human editors imply "facts" are in references when they clearly are not. In this case it was a minor, unimportant detail -- the location of the first meeting. But I have noticed several times wikipedia editors including "facts" that aren't supported by the citations.
