Yes, you can ship your twitter updates daily to Livejournal. But why? What is being accomplished? Tweets are ephemeral by design. If you said "my boyfriend's bringing me cake" at 1300 and "anyone at UCLA know if Parking Log 3B is full?" at 1500 and "Goddamnit I forgot to buy beets" at 1800, why should everyone know about all of these at once the next day?
Can anyone explain why you'd want to post your list of tweets to your Livejournal?
