What do the Twitter Accounts and Sync Options sync?

[kcoleman956]

under accounts & sync it has 3 things i can sync. Friend, tweets and Twitter. it may sound dumb but what do each of these things sync? i don't use the freindstream or any widgets, just the twitter app which updates when i open it anyway and thats good enough for me. I just want to sync the tweets from my contacts in people and im not sure which option does that. They could've worded it better.
