First of all, I have found this discussion informative. I have concluded that "bios" probably won't work and that the best course for those who enjoy "creative writing" is to simply do an interesting article from time to time.
As far as milestones, this is one subject that can be rather important to some, particularily newer cachers. Recognition is what makes the world go around. Any well run organization has a recognition program. The concept is very simple: Reward breeds satisfaction and continued participation. I don't think we can quantify what number warrants a milestone post. It could be 10 caches for some and 5000 for another, but if it's posted I think the veteran cachers and those who post of this site daily ought to take 10 seconds or so to acknowledge it. You'll not only feel good doing so, but you'll make somebody else, even somebody you don't know, feel the pride of accomplishment as well. There's no down side to this whatsoever, and a lot of potential to keep folks playing. On the other side of the coin, some folks might consider a lack of response to a milestone as a "slight" from the membership.
So in this light, my thanks to those of you that keep this interesting site running and for those of you who take the time to comment and keep it interesting.
I like mentioning milestones because everyone likes having a feeling of accomplishment. But there's no reason to keep mentioning the "big numbers" cachers over and over. Perhaps the Advisory Committee should encourage keeping milestone mentions to a minimum - perhaps at set milestones such as 100, 500, 1000 caches.
Sometimes the road less traveled is less traveled for a reason.
