Well, we had a few folks appear during the last sale with the Mount & Blade and Witcher 2 giveaways who were so used to Steam, and to other Steam-key-shops, that they asked in the forums---politely, and in all seriousness---how they could get their Steam keys. They honestly didn't know there was no need for those kinds of keys here and we tried to enlighten them about the GOG difference (most of us in a nice manner).
