One of the reason I visit certain blogs daily is because I use them as moderated blog filters to blogs I subscribe to indirectly. I don't know how many blog feeds "Dave" subscribes to, but by subscribing to "Dave"'s Scripting News blog feed, I am in-effect subscribing to all the blogs he is subscribing to except I rely on him to filter out uninteresting stuff like a client-side news editor. By subscribing to these hub blogs, I can keep abreast of what many thousands of people are thinking and doing daily. Isn't that great or what? I predict that we'll soon think nothing of paying money to subscribe to those hub blogs.
