WhatWG has a website, a wiki, forums, three public mailing lists, and a blog. It's clear that they want to have an open, collaborative process. But this is just going too far.
It's old news that Twitter is all the rage on the web. For me, though, it's not an option. I value control over my content too seriously to throw it in the hands of a third party corporation, no matter how "altruistic" they claim or seem to be. With corporations, the bottom line is always the same. I pay Textdrive decent money (for the services I get), so I know they'll be interested in protecting me and mine. So until I see a TwitPress that allows me to have http://jeff.cutsinger.org/status/, no Twitter for me.
