it has sort of lost it's appeal now and is full of drivel, but i mainly use it now to keep in touch with school friends who are now vanishing all over the world. good to see they're getting married, having kids etc. can be used for conversation starters when you see them again then/save having to listen to them babble on about it for ages.
now though, it's good for online dating. chat to a woman who's only got headshots on her profile, gather her name, look her up on facebook, see full body shots, see she's a bit too podgy and then stop talking to her.
boss invention.
