Why does everyone say "Thanks" in the comments?

to show gratitude. DUH

Thanks.

it's polite so yeah , but i use cheers

Is this for real? Somebody saying 'thanks' is a problem now? :O

Wow.. I don't care if people say an unoriginal "Thanks"! That's the only thing you get back when you give a game, I will never complain if that's original or not! At least they took time to thank you for your give away.

Because it is better than saying nothing?

Damn thankers going around thanking everybody.

just to be polite and greatful that someone gives me a chance to get a free game I will play after I finishing Defense Grid with all gold medals!!!

I always thought it was just post-count padding, but seeing here that people actually like to read the pages of thanks, I'll be sure to say it from now on.
