Are there any good webapps for sharing contact details with friends AS WELL AS people I'm doing business with?
I know there are programs out there like Bump which make this process "fun" and "easy" but I want some other suggestions. I don't always find others who use Bump and I'd like to know what you all think is the best way to get your contact info shared with other people. I'm obviously looking for apps which are accessible via the web as well, but if they have mobile phone apps which extend the service (or even offer "off-the-grid" solutions), that's great, too!
**EDIT: I'm mostly interested in solutions which don't require the recipient to be part of any membership network to receive my contact info.
