I can't actually remember who I am friends with online that I originally met on the amazon forums. Obsidian Blue for sure, and maybe some of the rest of you as well. I think Grimlock and I originally met on amazon. While I've not posted on the forums for years as a result of the troll infestation, it's still bittersweet to see them finally shut down. They were the first places that I found a group of people to discuss books on the internet. From the forums, to GR, and from GR to here, it's a straight line for me.
Edit - I think I met Char on amazon, too! It's all jumbled up in my mind now - hard to believe I've known some of you for five years or so!
