I know that some of you don't take on the trouble of signing up for Facebook, and I can understand that.
For anyone who does use Facebook (FB), I recommend a measure of hygiene: if FB ever asks you whether you trust another application or a web page, say no.
I use separate accounts for politics (including metapolitics) vs. for connecting with friends (whom I've actually met) and family. I don't recommend using one account for both purposes.
