What cycling fitness related social media/web do you follow?

[MattTuck]

There are plenty of cycling 'culture' blogs out there. I am curious what blogs, youtube channels, twitters, etc. that you all follow related to cycling fitness? Since we now have a twitter channel, I figure I should get with the program.

If you post something, could you describe if it is 1) on bike training, 2) off bike training, 3) nutrition or 4) other.
