I just thought it was incredibly "meh". It came across as something that was pulled together in a day (or even one evening), all that really happened was essentially a single name change and a few board names being mixed up. I dunno, it just seemed rushed and not all that funny.
Although I will say that it wasn't annoying or irritating and it was pretty easy to ignore it since it was only a day long, so it didn't deserve to have "rebels". After all, there wasn't that much to rebel against.
Oh and don't take this as some sort of whine, just expressing that I thought it was lackluster, and I understand why it was seeing as the mods have lives to lead and they had just came off the pony festival.
It's just that everyone talks about April 1 2009 like it was the best event in the history of the forum and anyone who joined after that date hasn't really experienced anything like it yet.
