Well uBookIt is finally here and yes it is 100% free No premium/upgraded versions will be sold and as long as you don't charge other people for the software (since it's free) you can do whatever you want with it. Use it for your own sites, for your clients, or charge other people for bookmarking services. This is still an early version so I'm 100% certain there will be bugs/broken sites so when you find them please report them and I'll make sure it gets fixed ASAP. When you report a bug try to be detailed as possible, just saying "digg isn't working" doesn't help. Feel free to request new websites and features.
