You can now also "follow" a channel and get notifications whenever a new show is added to it. (you can do that by browsing the channel).
A couple of other site tweaks: the browse section channel picker has now Prominent Channels and All Channels sections to help you navigate those quicker; the inbox link (that was next to the settings link) is now moved to the notifications popup where even no premium members will get a notification when they get a message.
As always - play around with the new features and let me know of any problems/comments/suggestions/critique you have. If you're not a premium member - please consider getting premium - it'll help me a ton with the costs of running and developing the site and you'll get cool features in return! Enjoy!
