I think wikis are a great way to discuss educational topics to help one another solve problems or enhance creativity. Just like all informational strategies that allow for comprehensive discussion and input, it allows people to visualize tactics that they would not have been able to on their own. The nice thing about wikis are that you are able to use one document to add information to and everyone can see the document as it is developed. From a technological perspective it is nice that the information is stored in one place unlike an group email that each participant would have to sift through to find all of the comments and information.
