I have used it and am not impressed. One thing is that on a route of 100 miles or more, it gets slower and slower until it is almost impossible to use. Due to some little glitch, it will occasionally start doing a thing where it links back to a previous point on each new click. So I like the idea- but the actual implementation leaves something to be desired, and sure doesn't make me want to invest my money in the site.
