No less an authority than Jason Kottke is taking up the "Twitter's data model sucks" mantle, instantly doubling the size of my little crusade. Actually, Kottke doesn't even attack Twitter, but rather sites that claim to provide Twitter-organization services, but it's close enough because it implicitly recognizes that Twitter doesn't have even a shard of organization on its own.
Hah - in typical fashion (and as Kottke predicted), Twitter itself has been flooded with tweets and retweets (and outright unattributed copies of tweets) regarding Kottke's statement. Many people are blasting it in order to put an end to Twitter Litter, somehow missing the incredible irony of their actions.
