We're not on Facebook (we don't post for free), so we we're left scratching our heads. Maybe we should check it out.

Nowadays I am active in five communities on Facebook (real communities with real friends with mutual interests), and I also see the posts of others on Facebook, and I use it to contact my friends and relatives too. I can learn from Facebook (gaining knowledge, getting information), so Facebook can be useful, if you use it properly. Many people use it mostly only to post and see funny photos/videos and quotes. While those are good, there is also an actual useful side of Facebook, which makes it worth to use, even if you do not earn a single cent from using it.
