I like this. Just yesterday I added an item to my wish list that is quite expensive. I know that a single person is not going to want to buy it for me. But if several of them contributed, it would be more realistic.
Edit: It also makes a new way to get tips/donations. People might be more likely to donate if their money is going to something they can see. You might even get people to donate a little more if they see you are very close to getting the item.
Well... I mostly use my Amazon wish list to keep track of things that I will likely buy myself in the future. I don't really expect people to buy them for me. So I did not sign up for the site. However, it is a great idea and is something I am likely to make use of at some point. I just don't have a need at this moment.
Don't worry. I didn't feel attacked at all. I understand the need to get feedback from users (or non-user in my case) to improve things. And it was not even the concept that held me back... just lack of need at this time. Generally speaking, I'm not one to sign up for something until I actually plan to use it.
