I've heard of Seth, but don't follow his stuff. The comedian Richard Herring has done a daily blog since 2002. I don't read that either, but I am a fan. I listen to some of his podcasts and he has done a lot of those too. There is just not enough time to consume everything I would want to.
Looks like there are other long time daily bloggers out there... I agree, not enough time in a day to follow everything.
