As with anything, there are always "experts" on any given subject, blogging has more than it's fair share, although I think it's great that some who are actually "doing good" on certain sites try to help. I use many strategies to try and increase my audience, usually to no avail, but I still try. the one thing I try to do though, is offer good content. Maybe that's my problem, some feel it isn't good enough! :)
