From time to time I go through the list of blogs that I follow (currently 61 of them). I tend to mainly get rid of those that I either no longer read, or rarely read anymore, just to reduce the amount of crap that I have to filter through when I check for updates. I also go through and generally remove any blog that hasn't been posted to in over 6 months, just to remove the dead wood. So if you're a bit behind on your blog posts then I suggest you put pen to paper/fingers to keyboard and post an update just to keep your blog ticking over.
If anyone is reading this thinks I might be interested in following their blog, post it in the comments and I'll check it out. You might find yourself with a new follower.
