What he's trying to build already exists (http://identi.ca http://identi.ca), but will never succeed in any form: the only reason Twitter has stayed so constrained is because it's not federated. Only a walled garden can avoid basic features that way -- an open platform wouldn't embraced and extended so shittly. What he actually wants also already exists, and he's using it successfully already. It's a goddamn blog.
