| I could imagine setting up the following cards right away. And by "card", I'm not specifically referring to a piece of paper, but perhaps some kind of contact-info-related digital object. * BFFs * Recent acquaintances * Close family (reasonable people) * Extended family (think annoying newsletter emails) * Co-workers (cell number included) * Clients (cell number definitely not included) * Spammy business contacts (vendors) * Travel (something I could hand out with temp hotel and phone info, etc.) * Japanese (my wife is from Japan, we have lots of friends here and visit there often) I could also imagine handing out specific cards at various social functions. For example, at a writing club I used to attend, I'd want to provide a link to my portfolio online. I'd never ever want anyone else to read that embarrassing stuff though. In another case, I used to attend a board game club, and it would've been nice to hand out cards with links to my profile on boardgamegeek, meet-up profile, etc. It seems like this would work best if the exchange format was simply vCard or some other open format. You get to control who gets what at the point of exchange, and they can consume it into whatever system they like. There's no after-the-fact futzing with tags or permissions or contact management; it's just a system to control how you present yourself. The whole idea is probably DOA if you can't interface with the rest of the world's contact software. Maybe you allow connections if both people in the exchange are users of your service, but you wouldn't want to take it for granted. As an aside, this got really interesting when we considered the "hot girl in a bar" situation. Let's say she gets asked for contact details many times, it's too loud to hear names or whatever, so she might need to snap a picture of the guy at any point of exchange, then review and modify permissions later. But that seems kinda fussy as a system. |
