I have the same problem... being a working mom, not all the time can I read all the blogs I have followed. But Google Reader is one way of speeding things up. =) Organize the blogs to your liking and you will be one step ahead.
I tried going through my blog roll before but some of them are not updated so most of the time I keep visiting the site with no updates. :(
Google reader is a really great tool. Getting used to it and browsing on it 2-3 hours a day would be enough. ;)
I'm also a Google Reader girl. Blogs are organized by category into folders so I don't go crazy. I also use the Google homepage (iGoogle) so all of the headlines of my top blogs show up on my home page whenever I go online. I do try keep up with everyone, even if it's only popping in once or twice a month to check in. Twitter help a lot.
