When it comes to simple neat products, I am rarely excited. Thumbtack changes that.
Checkout http://thumbtack.livelabs.com - this is exactly what I needed online.
Find a product I like, copy&paste it to Thumbtack. Like right now I am in search of a place to live closer to work, so I have clip outs from different places online all in one place in a category Apartments. Thumbtack shows a preview if there are pictures and even has plug-in to show them on the map, if it finds address info. Really cool!
Thumbtack also lets me publish and collaborate on such collections.
