I like NXT, and have a few K of them to have and hold. It is a genius project overall.
The asset exchange is good, though it's hard to browse through and find assets.
The marketplace needs a way for feedback and voting on the quality of the item sold in the marketplace... something like fiverr.
Haven't checked out the voting system nor the plugin system yet - lots of development going on.
Cheers
