Keeping on top of blog reading

I read so many blogs that it gets ridiculous at times. I comment and comment and comment and it really does not reflect with comments back to my blogs.

But I enjoy reading them, I learn, gain inspiration and become a better blogger myself.

My Google Reader does fill up to quickly though and sadly I am going to have to cull a lot of blogs very soon. It's a sad fact that I have to assess what each one brings to my busy blogging life.

How do you deal with blog reading and commenting?
