Perhaps, but I don't make a habit of reading blogs about jobs I don't currently have from smaller companies. Not that I have anything against them, but you still have a discoverability problem.
But that's the problem though. At that point you either have to have one of the top 10 smartest and most interesting people in your field willing to write for you and bring their clout to it, or you have to have a network already strong enough to bring in the staff you need. It's almost literally impossible for that to be the case outside of a tiny set of companies, and that's why the current hiring system exists.
