I think you missed the point of Pinterest. This is to Pinterest what iPhoto is to Facebook.
But I'll be honest, I was first interested in Pinterest because I thought it would be a lovely bookmark aggregator. This does that pretty well from the look of it, but it's definitely a self-hosted image bookmarker with a Pinterest-esque interface, rather than a self-hosted curated web.
Might be splitting hairs over a title, but the difference is significant.
If you like the point of Pinterest, use Pinterest. If you just like the look of Pinterest, you can use Pinry.
I could see something like Pinry being useful for creating communities that respect freedom of speech / information / image posting, so long as the content is not illegal.
I know (many) people with anorexia. They are amazing at hiding stuff. (Fishing weight shot sewed into bras; heavier weight sewed into hair scrunchies. This made the weekly weigh-in easier to pass while still starving.)
I'm glad Pinterest has made the gesture, but they'll never win.
For certain definitions of lovely, consider http://pinboard.in/
And the best part about it being paid only is that I get some assurance that my bookmarks there will stay available.
