It occurs to me that there are people with up to maybe 250 "friends" on Facebook, who read their walls,. There are also people with 3,000 "friends", who obviously do not even look at it. It makes sense to subscribe to some popular content providers, as an inexpensive way of browsing information. It does not make sense to expect any of those people to read your posts, This also applies to Twitter.
Why then do I bother to post this? Purely as a diary entry, and possibly as a ping into the dark to see who answers.
