I had friends that I had their AIM name but I never knew their email address. Could I ask everyone on my friends list for their email, switch to email & email them, hope they check email at the same time they sign into AIM, and when we're both online ask them if they got my email? Sure... but that seemed like more effort, and writing a bot seemed fun :) And it's nice to have one interface with all the context.
