Keeping in touch is social
And if you have an iPhone or iPod touch, Ping! seems to be a good way of doing it for free.

I gave it a whirl and it seems quite good, I just need to get more people using it. (hint hint)
So please give it a try, I think you will like it, the only drawback of applications like this is that there are so many, and apathy kicks in before enough people start using it en masse. Tell people you know about it too, and drop me a message to chimerax
