I forgot to mention the best thing about Wishpot...if you see something on someone's wish list that you want to buy or have already bought for them, you can "reserve" that item so they don't get duplicates.
You can also choose to hide the reservation from the wish list creator. So, everyone else will know that the item is already reserved, but the wish list creator won't know that someone is planning to get them that item.
Helps avoid the hassel of friends and family having to ask around to see who's buying what off of a traditional Christmas list.
It might seem greedy or presumptuous to create a list of things you want others to buy you, but I'm in the camp that it makes things SO much easier for the gift giver. They're able to quickly pick out a gift you'll love and you get exactly what you want. It's a win-win situation.
