I know I am an old grunt when it comes to these things. But one option is to just ignore most of these services. I like being on twitter as it keeps me in the loop of what's going on local Web/Tech scene, but I don't see any reason to use any other social service.
And even with just casually reading my twitter feed I can tell from the top of my head that you were sick this sunday, andraz went to paris and tomazstolfa was playing golf, which is a bit of overload .. for example I have no idea where my sister, father or mother were this weekend.
