For what it`s worth, I think that blogs are a great communication tool and I currently subscribe to over 40 RSS blog feeds on various topics. Unfortunately the Land of Blog is getting a bad rep because although anyone CAN start a blog, not everyone SHOULD (I can sing in the shower but no one is going to pay me to perform at Carnegie Hall). I routinely add/delete several feeds every week and I`m looking forward to following nhgnikole`s blog but I routinely kill off any blogs that don`t provide fresh content or aren`t updated on at least a weekly basis. That`s just me. Blogs that I follow are ones that give me insight into topics I`m interested in (startups, home theater, technology) and I`m not interested in reading rants or hearing about Fluffy`s hairballs.
That being said, I agree that outdated blogs are an issue. I`m tired of looking through search engine results where I end up on a blog that hasn`t been updated in three years. Either the search engines should bury stale blogs on the 14th page of their results or blog sites should expire them after the content hasn`t been updated in over two years. Maybe Blogworld needs a good old fashioned brushfire to burn off the deadwood.
