Online networking comes in many shapes and sizes. Longtime tech dude Burt Lum — yes, he of the suspiciously familiar homepage designs — has pointed me at Ryze Business Networking.
A simple, organic design, useful cross-links for subject areas, contacts (including a personal profile), and the like, with growing networks for Hawaii, bloggers, and online media.
You've got to sign up to do or see anything, but even without the heavily-promoted premium membership upgrade, it's pretty neat.
