I am a bit nonplussed by the blog lists that this site say are popular. Could it be that if the subject matter strays from the original it then becomes unpopular?
A blog with 3 responses is not what I would call popular.
The reason I mention this is that my blog "Treat the patient not the Disease" was well represented with a lot of useful information from many people but it is no longer there. I am not saying this because I started it. I don't care who starts it but if the issue is well represented and the feedback is helpful then why does it become effectively unpopular?
