The Business of Blogging

I've been noticing that blogging has become a business for those that own it. Now with AdSense people can get an additional sense of revenue. I would think that the ramifications of this is that people would begin to write things that would generate revenue and not be true to themselves, or they would stick these ads in the most conspicuous place ...which is a general annoyance to the readers itself (a long list of ads before i can see th post...hmmm ... no fun)...it seems like 1995 all over again...
