Obviously if you're interested in HS track you're going to write something like, "Dyestat", whereas if you're primarily interested in college track you might write, "Trackshark".
Granted there are some sites that cover all age groups, but many people have a personal preference. I for one enjoy HS track, even though I'm not in HS. So I'd say Dyestat, although I don't like all the younger kids (mainly freshman age), but they learn. In all honesty, there are crappier responses on this site and worse logic than Dyestat, but that maybe due to the anonymity of letsrun.com.
