LOL - so "unreliable" it's the second Google search result after Wikipedia with a more accurate background. "Unreliable" is from a Wikipedia "editor" who has the time to make 50,000 edits, many of them reversions, to keep Wikipedia an island. That isn't a Wiki - that's your personal website when you can't get visits from others.
Look - for those who care to follow - there's even a name for this follower who (in his mid 50s) makes 50,000 Wikipedia "edits" ... a delitionist. It's not a real word - they made it up (Personal attack removed) https://meta.wikimedia.org/wiki/Deletionism
OMG - a deletionist deleted a rant on my talk page. In any event, I'll leave it deleted for posterity. And because I've come to realize many Wikipedia editors are actually pretty smart. Still, I have no idea why they spend so much time on Wikipedia rather than writing blog posts that will be attributed, won't be deleted, and won't be monetized by a pseudo-anonymous group of people in San Francisco whose sole purpose seems to be needless fundraising. In any event, Ruby was supposed to be a conglomeration of people but nobody else contributed so I switched to my personal page, here: https://en.wikipedia.org/wiki/User:Olenick. It's older than Ruby though, to be fair, I'd entirely forgotten the profile existed until Wikipedians looked it up and reminded me. Stop by, say hi, and delete stuff.
