I notice that OpenSolaris has very few "users" listed on ohloh.net. Lets bump it up. If you use OpenSolaris, why not go ahead and create an account on ohloh.net, and indicate "I use this" for OpenSolaris.
While you're there, if you're grateful, you could grant kudos to your favorite developers. And if you have any contributions of your own (pushes to ON), go ahead and claim those to (search for your name or login in the "people")... it bumps your rank, and makes your "kudos" worth more when you deign to give them out.
