Dutch social network Hyves lets you sort your friends into groups. You can make a maximum of 7 groups, of which 'family' and 'business' are set. You can use these groups to send a message to part of your friends with one click, for example. Or place a 'WhoWhatWhere' which not all your friends are allowed to see. No one can see who's in which group. In future you'll also be able to use friends groups for other parts, such as photos.
Future vision by Erwin van Lun
The amount of friends is becoming less important as a status symbol; the amount of contact moments you have and the depth of them, how social you are, that’ll be a lot more important. Currently you have to sort your friends groups automatically, but later social coaching brands will start to give you advice: “Does Marijke, your colleague from work with whom you exchange only business notes, really see all this personal stuff?” That’s how social coaching brands will understand your private life ever better. This is a start.
