I'd like to think of a bitcoin address as just another item in the 'personal information' list, like a regular address, phone number or email address. I think it should be an entry in a users profile. Then, when I feel the need to send somebody some money, I can just look it up and send some. Of course, people may also choose to not put it in public display, just as with phone numbers or email addresses. It depends on the situation, for instance one might not list it on a public forum like this. When it's listed in a profile, I definitely don't see it as solliciting for change.

I'd really like to have a bitcoin address for all my friends in my address book, then when I borrow something or have to make a quick transaction, I can just browse my smartphone for the right person and send some coins!
