I recently crossed 1,000 friends on Facebook. Am I actually friends with a thousand people? No. Not even close. If I were using Facebook to only be in contact with people I consider myself at least somewhat close to, I’d probably have more like 100 friends. Maybe less.
For a long time I haven’t cared about using Facebook in this restricted way because I’ve basically been using it like Twitter — which is to say, with the assumption that just about everything is public (and I have a filter for the few things I don’t want public). The problem I’ve been encountering though is a massive amount of quasi-spam.
