Wallwisher

Wallwisher- Like most of these 2.0 tools, I had never heard of Wallwisher.  It reminded me of the wall you would find in college where people posted jobs, apartments for rent, tutoring sessions, etc...  After using the tool, I realized the tool could be a method for receiving feedback.  Professionally, I think students would be more apt to provide positive and negative feedback if they could do so in this manner.  I can't think of any ways to use this personally, but the ease of use makes this ideal for feedback purposes.  The ability to add links is probably the best feature.  In a way this is pretty comparable to twitter.  I think twitter can do all these things and it is a form students are already familiar with.
