Ask HN: idea about a social checklist sharing website

I was thinking of doing a small side project of creating a website where people can create checklists where they can be shared and found by others online.

For example I go hiking often and have a checklist of + sunglasses + vibrams + blister band aids.. etc..

or volunteering + duct tape + permanent pen + sticky notes

Any two cents if you guys would use it or what kind of functionality you would want?
