I had my own site (mental health oriented) linked from my Youtube, and a real life friend knowing my YT. When I realized I was EEEP, and I deleted the link at once.

For me, mixing my online life with RL is a big no-no. Some online friends have my phone number and address, and I met someone from online IRL. That is all. My friend could use all my bookmarks and logins when I'm away and she uses my computer, but I realized she's not interested enough to spy on me. Which is nice. Still, would hate being found out by anyone else IRL...
