Actually doing it this time!
How to participate in the liveblog chat: Option 1: Whenever you watch the episodes, comment on this post as you watch with whatever responses you feel like posting! Option 2: Go to http://webchat.freenode.net/. Enter a nickname, then for the Channels field enter ##rabbitcube, and finally fill in the Captcha and hit Connect! We’ll be watching MLP there starting at 1:00 p.m. EST. This is one hour before the usual time.
Afterwards, I’ll update this post with the chatlog.
ETA: Chatlog after the cut!
