Oh, there are already many discussion/tutorial sites about yo-yoing. I don't intend to replace them, but to offer something they don't: a single place to coherently store pictures of, and more importantly, data about, your yoyo collection. Most of the message boards allow photo uploads, and you can always write descriptions in the posts, but that data is scattered.

I have thought some about montization (mostly in the context of "If this thing grows, how will I pay for hosting beyond my own personal/hobby threshold?"), and have two ideas:

1) fremium - subscriptions for the "serious" collector (more data fields, etc.)

2) ads from yoyo manufacturers/organizations (there aren't many, hence I don't think AdSense would really draw much revenue; plus, I actually have a few contacts at Duncan)

If I had to pick one of those, I'd rather pick #2 - I can't imagine this site, as I currently plan to build it, would add enough value to justify subscriptions.

Anyway, if you want to pick it up again, I recommend: - http://www.theyo.com/yoyo/ and http://www.theyostore.com/ - http://www.yo-yoing.com/news/ - http://www.yoyonation.com - http://yoyowiki.org
