Online communities change over time. Go to archive. org and look at one of your favorite blogs, three years ago. I still think the best response to a blog that disappoints you is to get 4-5 like minded people and start your own. Not because the complaining is or isn't justified, but because it adds something to the ongoing conversation.

It's not like there aren't five interesting people in here who couldn't start their own collective blog. Or even better, write something that will scrape the sites of five BB posters and create a metablog.
