Tim announced the cancellation of "Wonderfalls", and posted some more until he left, then he said there's pretty much nothing that can be done to save the show (maybe for DVDs), until he left, and again for a couple of posts.

Various posts from Tim, from here to here.
Is it considered a meara if I don't respond to anything?
So, in my absence (deep breath): Tim visited for a post, and then from here to here, and then again from here to here, and also from here to here, and there was a post, which got a continuation, and then from here to here, another solitary post, another here to here, again from here to here, a couple of posts, some more until here, and again until he left.
I'm never ever going to be able to catch up on the actual content of all this (let alone the whole other 5000 Minearverse posts), so I hope he (and, well, the rest of y'all) didn't say anything interesting. Only, well, not really.
