Sure - but most people either use a twit client (a small app that runs on your PC and/or phone that updates you on the tweeters that you're "following") or opt to get an email when there's an update. FYI: I use tweetdeck on my PC and PockeTwit on my Windows phone, but there are a multitude of clients out there. (...and, since you mentioned it, I also have my Facebook status update to my personal tweets and my LinkedIn status update to my preofessional tweets, but that's probably a little extreme )
Coming soon to a home theatre near you (it's a blu-ray in 1080p with 7.2 surround sound, so make sure your technology is up to it ).
Seriously though, we tweet the little stuff - we don't tweet every minute of every day (actually, we average maybe once or twice a week), and it's mostly hot topic, retweets and system status messages, so you'll still want to either use an RSS feed (IMHO the best option) or go directly to the wesbite for the full LAVA experience.
Actually, @lavag is most active during NI-Week - it's updated with schedules, good session previews and summaries, lunch meet-ups, and info on where the LAVA crew are getting on 6th Street in the evenings for beer and tequila shots But just because it's most active during NI-Week doesn't mean that there's good stuff going out on the wire throughout the year...
