That sentence is starting to annoy me, every single website I join asks me what I'm doing, why on earth do they care?
Why can't they all just sync their status with facebook or twitter? Well, very few do but the majority just have their own field with no way of synchronising it with any other site.
As I've said before, the least thing the web needs today is another place to store your data and no site out there that aims at gathering all your information in one place does just that.
Every website that promises to "put all your social networks in one place" or "centralises your on-line identity", they all end up adding at least one thing: the net work part; they all ask you to add friends...
While I was thinking of this problem, I did come up with a solution that doesn't involve making friends to share things with your friends without having to make different friends... as a matter of fact, it even helps organize your contacts from the different places.
I might go for it one day, but I'm still working on Deskiyo and it's still interesting. So this is just a thought.
