I never really "trusted" Facebook or Google+. That is to say, I never expected them to respect my privacy or keep my secrets. I'm not too secretive online anyway, and what I do have to hide, I just don't post. But it is very clear that there is a great deal of corruption inherent in a business model which is based on concentrating the personal data from millions of users and selling that data to advertisers. At the very least, there must be a free alternative. But for that alternative to be viable, we need to use it. Identica has been around for some time now (and I use it -- I'm "digitante"), and Diaspora is (after a long hard start) finally getting some wind under its wings. I've used it, and it's Good Enough. In fact, you'll find it's pretty similar to what Facebook or Google+ offers, although there are still some rough spots.
