While high school and undergraduates don't often have access to the high-cost infrastructure needed for hard science or biological science, there are vast amounts of data available that enterprising individuals can crunch for next to nothing, which can be picked up by other institutions as well.
Like any data service, it will be as good as its data - without a big concerted effort to gather data it will soon die.
You need to reach out to science fairs, big and small, as well as Science Research programs and convince them to post their work here. Also in lieu of citations awards earned would help distinguish the more decent ones. Downloads may also be a good metric to measure interest
It's cute. I would probably never read anything there. I wouldn't trust my own projects and stats from high school and I actually do this for a living now, so why would I trust some random's? looks good on applications though, like debate club or something, announces your acceptance of the norms of the scientific society you wish to join.
