How the heck do you keep on top of Tumblr?

[firecat]

I really like some of the alternative/political stuff being posted on Tumblr, but I find it difficult to keep up with because of the lack of a reading list feature. If you keep up with Tumblr how do you manage it? Bonus points if your answer is something other than "refresh it every 10 minutes all day." :-)

I just go to the tumblrs of people I think make good posts every couple of days.
