Not a lot, really. I have a friend who posts fairly regularly and since she lives in Florida and we see each other every 5 years or so, I can keep up with what's going on in her life by reading her blog.
Then I read Yarnstorm
but she's not posting regularly over the summer.
The rest are just hit and miss sites I get from links but really nothing else I read regularly. I guess I don't have that much time after reading posts here and posting to my own (neglected) blog to read much more. When I keep up with my own blog (updates coming in the next day or so!) it takes a lot of time to get everything the way I want it. By the time I am finished I am ready to log off.
And yes, 60 to me seems like a lot of blog reading!
But, if you want to make it 61(what's another blog between friends?) you can check out my blog. I love getting more hits!
