Slinkset is maybe not an original idea (corank is pretty similar and was around first) but it's a good one and very well-implemented. You don't make money by being original. You make it by being good. Allowing people to start their own sites trivially (not counting some goofy domain issues I had, I think NHN took me 10 minutes or so to set up) is a good idea, and one that has been popular since before the first bubble.

This is my first time actually checking out Slinkset . . . pretty cool app. Do they have any paid features yet? What's their business model?

Nevermind:

for the time being Slinkset is offering its hosting service free of charge, with plans to introduce a fixed fee in the future.

As an owner of a handful of slinkset sites, I'd be more than happy to pay a fee for additional features/options. It's been a huge hit for us.

Precisely. We're working on premium features.

I like the look and feel, have to try out Slinkset.
