Facebook is an interesting platform. I use it entirely for social purposes, keeping in touch with old friends who moved away and organizing/publicizing upcoming free events that my posse puts on around town.
I have read about the fact that it shows advertising, but I don’t see any ads on it, thanks to AdBlock Plus on my desktops and a 3-year-old app on my phone. So as far as I’m concerned, it’s not a viable economic entity.
The timeline thing where most people don’ see stuff is a bit of a problem.
Perhaps we need a thing that’s just like Facebook but without the need to make money. Hmmm. Amazon ought to run it! They know how to not make money.
