Another way I keep track of things I see in a store/magazine that I like is to take a picture of it.
My idea is essentially a "wishlist" app.
1) You see something you like in a store, take a picture of it. 2) add a title/description and save it.
You can keep track of the things you want, maybe the price/location you saw it, etc.
However, you can see what your friends want and either - add to your own wishlist, ask them question's about it or even make recommendations.
The point of it is to track your own items, not create a "idea list" for friends and family who are shopping for you.
Thoughts? Criticism?
