This is not a copy cat. Jelly/Jelly Talks was started by a friend of mine (potentially before Fluther existed), and I think refers to the jelly from peanut butter and jelly, not jellyfish. Either way, it’s a really cool co-working thing that has nothing to do with Q&A or anything related to Fluther.
If you look further into it, you’ll see that I’ve been attending these “Jellies” (and yes, I did notice how strange it was that it was the same name) including the very talk in the video. I even had lunch with those guys right after this.
Anyway, sorry to disappoint everyone, but there’s no need for rioting in the streets. This is just a symptom of a really cool word. :)
