what do you think i have been working on this very hard what can i do to make it better http://www.crashdiary.com/
Very well done! Easy to read, nice pic to grab your attention, just generally very good. I'd recommend much more content but you're probably on that already
Maybe you could provide a strip of thumbnails (of crash photos) that people can click on to enlarge. That wouldn't require adding content and people would stay on your site for longer. You could also search article directories for articles on famous crashes? Not sure if that would yield much results. Good luck!
The idea is probably ok - the design seems a little plain and it is obviously just a site made for adsense
Good mix of funny and horrific pix - youtube videos would help - lots os scripts available that you just enter sets of keywords and it pulls up pages of youtube videos on topic. Add categories - racing/sportsetc
