A few things:
1) Firstly, great list. Very comprehensive! You'd think that Runner's World would pay someone for this, or at least be interested in having compiled it themselves by now.
2) LetsRun is great for feedback and spreading the word, but this should live somewhere outside of LetsRun - the problem is that nobody's going to remember that "the latest updated list is on page X on a Y page long thread". Do you have a Tumblr page or something you could put this up on? Any kind of constant URL that just gets updated with the content.
3) I agree with your criteria except with the gimmick times. It seems like allowances were made with strollers and treadmills (why not have fastest stroller runner with a 6 month old, 1 year old, etc). Better just to take them all out, or include them all, rather than have this gray area always exist. People will always challenge it and it doesn't make sense.
4) Athlinks. Why no mention of it? Do you use it? If none of this information is on Athlinks, and if you've verified it then you should at least submit it. There should just be one place to verify someone's time rather than scour the internet. Athlinks has been around for a while now, it's a staple. Then link the Athlinks results to each person's time on your list.
