Screenr

Screenr-This was a close second to Diigo in the list of favorite web2.0 tools of the week.  I had no previous experience with this tool, but after using it I could immediately see the benefits of utilizing such a tool.  This is a tool I can see myself using professionally, especially in my math classes.  The simplicity of the tool makes it useful for all teachers and this is a tool I will recommend to other teachers.  The amount of times I wish I could just record my screen and add some audio is too numerous to recall.  I don't know of any comparable tools, but this one seems hard to beat.
