Everything they have here (and some more) is available to anyone who whishes to get it, directly from Valve: http://dev.dota2.com/showthread.php?t=47115
I actually just started looking into trying to do that though I'm not sure how exactly to use those URLs. Just thought it would be a cool thing to incorporate into the site and would be easier for the average person to use in some spreadsheet form as opposed to the XML form you get from the API.

Don't know if this in inb4 as there is not search feature for the forum (i think) but I think it would be great to be able to download your data in some form of spreadsheet format so that people can run their own analysis on it and create graphs and custom statistics.
Also, a side suggestion: heroes you win and lose AGAINST the most (pingpongphenom's idea http://www.reddit.com/r/DotA2/comments/11dn35/wishlist_new_stat_for_dotabuffcom/)
