Great work on Strava, I love it.
I guess the growing number of segments has popped up on your radar as well as something to keep an eye on. Since anyone can just add them, there are segments within segments, segments that are almost the same and segments that should just be personal ones since they aren't special in any way.
Are you having plans on how to control the segments? Maybe a voting system might work; if an X number of people who have ridden someplace can vote whether or not a segment is valid or not, that segment could move into the approved category which shows up after your ride and then some link to check your results on all the other (not yet) approved segments.
Hoping to hear your thoughts on the issue, I feel the jungle of segments might become a con for Strava and we wouldn't want that! :)
