RinkAtlas now supports social bookmarking through our "Bookmark & Share" button on the toolbar. This feature allows you to bookmark rink locations in Digg, Del.icio.us, Facebook, MySpace, and about 30 other sites.
This feature is made possible through AddThis, a company that specializes in social network integration tools. AddThis is a local company in my area, and I've met with two of the company's executives in recent weeks. I like what they're doing, and I think it provides real value to RinkAtlas users.
If you think the Bookmark & Share button is helpful, drop me an email at daiello [at] rinkatlas.com
and let me know how you are using it.
