I barely have enough time to play the games I like, let alone searching through pages and pages worth of text-only subject lines of games that may be in genres I have no interest in. That's why whenever I feel like looking around for something new, I end up going to java-gaming simply because they show preview images in their forum posts. I can scan a huge amount of games until one grabs my attention in a very short amount of time, rather than farting about clicking on text-only links going by nothing but titles like "New flappy bird rouge like on mobile now free play now check out our game now free hotdogs".
I suggested a few weeks back that we have an in-development forum like tigsource, but tigsource is already such a good resource I don't know if just doing the same thing has much worth. I know many more people on GDnet than tigsource so I myself would much rather post here, but I could easily see people just ignoring it.
