Make and Share Lists With Listly

I love making lists. If you share that passion, you will appreciate Listly.  It is a free service (with a few premium options) that lets you create and share lists of resources. You can make your lists public, which is a great way to look smart (assuming you are a thoughtful curator). Sharing options allow others to spread your lists to various social media sites.

Cost: Free and paid versions (from $9.99/month)
