I NEVER, never, never use my Facebook login to sign up for anything… if it is required I don’t join. If you want to know the brand of toilet paper I prefer ask Google, I use my Google identity to sign up for everything… perhaps because I have an android phone so Google knows everything about me anyway. I try to keep my Facebook page, dull, boring or politically incorrect enough that people who ‘friend’ me and don’t really know me, ‘un-friend’ me fairly quickly :-) I just found Medium a couple of weeks ago, and so far I’m enjoying reading the thoughtful posts here.
