As the this medium is getting more and more attention, it is also being scrutinized by the ad agencies.   As many people have noticed, it is still dirt cheap to advertise on the blogs.   Limited audiance but highly sought after demographic.   Things have started to change and the liberal advertising network has been created to take advantage of it.   Sites like DailyKOS and MyDD and others provide a community of liberals and progressives with much to contribute to the present political arena.   TalkingPointsMemo's Josh Marshall is creating another community at the TPMCafe and should be online soon.   As you can see from the quote from the liberal ad network below, it is not just a matter of a few hundred hits per day that the major blogs are drawing nowdays.   Through comments and diaries (blogs within a blog community) people are afforded a outlet that carries more weight than individual blogs like mine that do not get as much exposure.   This also means diversified content and more meaniful reactions than message forums and bulletin board systems considering the extra exposure to more people.
