Week 7, Thing 17: Learning 2.0 Sandbox Wikis

In the Maryland Library Sandbox Wiki I added a favorite book on the page "What I'm Reading." I doesn't really seem right to make changes to a page another person wrote. For example, My Favorite Places in Ohio is no longer her list of favorites if other people add to it. I was interested to read that someone made a Wiki that is a list of things to do. I know you can keep the Wiki private, but why would you put your list of things to do in a Wiki? Is it easier to get to, edit??
