Sharing information with Friends

I think it would be a good idea for IMDB to enable a capability where I can share my lists with other account holders that I choose. That way they can see the movies on my watchlist for example and we could know if we want to watch something together. Other things could be specifically shared too like interests when they are added. I can see Reviews are set up so you can show them publicly which is fine, but having a way to share things beyond just a rating number with other accounth holding friends might be something of value as well.
