I was reading something about beta sites that are invitation only, and how some seem worthy of such exclusivity whereas some don’t. Justified or not, there are a bunch of cool new-ish things out there that require an invitation. Joost comes to mind, as does Natuba. I already have a Natuba page (thanks Richard), but I thought I might like to try some other nifty “Web 2.0″ thingamajigs out there, so enter inviteshare.com. It is a site simply devoted to passing out invitations. Cool. Got my Joost; trying 8apps. You never know what useful new tool you may find, so give it a shot. Then again, maybe I should have kept it to myself… less competition for the oh-so-coveted invites. Or not.
