You're judging to quickly. Take a step back and reconsider. The point is in the use-case, not the mechanics. He is allowing people to blog ad-hoc, using twitter as the glue to otherwise loose content containers.

Hey now Accusey Adam (or is it Conjecturey Constance?), put down the pitchfork. There's no need to accuse people of sockpuppeting/gaming just because you don't like their project. It's hurtful to hear people call you a cheater when you just want to get feedback on your project.
Tamal has a pretty neat looking service (yes, one that's been done before, but still pretty neat). I've seen SPLASH PAGES with zero functionality get more votes on HN; why shouldn't Tamal get his 15 minutes?
I don't get why this is #3 on HN right now.
