Case in point: Evil Genius giveaway
I've seen a few people saying they thought it was a giveaway for Evil Genius 2. I personally don't understand how someone can think that the game being given away is EG2 but then again, I guess people can't be bothered to read descriptions. And apparently, using capital letters is not enough either.
So, my advice to whoever puts up those giveaway pages... Have the game titles written in all caps and use an extra bold font.
Maybe that would have prevented people from grabbing a key thinking it was EG2 and then dropping said key on some other forum when they realized it was actually EG1. Heck, someone even created a giveaway for EG2 on steamgifts... *facepalm*
