Might try any BUT a random giveaway. This way someone who really wants it will get it
OR, another way to ensure someone who really wants a key gets that key is to SAY what the key is for instead of blindly just dropping the key. I'm not quick at all in this thread but still check up on it from time to time. I would hate to think I got a Showdown beta key or a DOTA key or another of the umpteen other beta keys floating around these days or even an actual game key for something I do not want or wouldn't even bother downloading.
If I happen to time it right and see a key that was just dropped but it was identified as somethign I do not want, I'd let it go and let someone else go for it. As it stands now, if I time it right and just see a key and nothing else, my curiosity would get the best of me, and I'd try it. If I got it, I'd say thanks but that key for Showdown, etc would really be wasted.
The generosity of folks dropping keys is great but just adding the title would help a little bit more in getting that key to someone who wants it.
I'm sure I'm not the only one who thinks people should post the games title when they drop a key.
