Twittering to myself | Social Signal

Twitter seems to be the new addictive social networking app on the block. (For those new to the phenom, it's a site that lets you tell your friends what you are doing RIGHT NOW, and to see what they're doing, too.) But I haven't been able to get into the addiction cycle, because I don't have any friends. :(

Why? Because unlike other social networks -- Facebook, LinkedIn and Friendster spring to mind -- Twitter doesn't provide a way to mine your address book for fellow Twitter-ers. As far as I can tell, if I upload my address book to Twitter, EVERYONE gets an invitation to be my Twitter buddy, whether they're Twittering or not. I can see how this helps to spread Twitter, but since I don't want to annoy my entire contact list with invitations to all the social networks I check out, it makes it very hard to get up and running on Twitter.

So consider this a triple request:

1. If you're using Twitter, ping me or add me to your friends list.
2. If there IS a way to make Twitter scan my contact list for fellow Twitterers, please let me know.
3. Twitter, if there ISN'T a way to scan my contact list for fellow Twitterers, could you add it? Or could you at least allow me to scan my buddies on other social networks like LinkedIn and Facebook -- not just LiveJournal, which is the only one you currently connect to?
