Every once in a while n00b will ask a question about certain isms and they just have to look a little harder to find the answers to them. Lisa said it best once when asked about a certain award (ugh!): nothing like a good scavenger hunt.
Nothing official, no. The awards aren’t presented in any way other than being there, and the rest of the stuff you mentioned are things belonging to this community as inside jokes and site culture. That usually isn’t something mentioned in most introductions.
Fluther doesn’t have any of that, at least as far as I know.
And if it did, it would totally have to mention the Yarnpocalypse. :)
The wiki changed over a few months ago. Everything was lost in the transition. But it is still there and I had pretty much forgotten about it. http://www.jellytastic.net/
Go nuts if you want to add to it. Or send me a pm if it won’t let you edit or add.
