If you're looking for a way to force yourself to work over the summer, consider joining the Summer Academic Working Group. It's a great way to get feedback, have false deadlines that force you to actually write your sh*t, and stay motivated over the big summer lag. I participated last year, and am helping with some of the organizing last year, so if you have any questions you can post as a comment.
We are happy to announce the 2008 Summer Academic Working Group. This peer accountability and feedback system allows users from anywhere in the world to share documents and feedback. Working group participants participate in "clusters" around a common discipline, theme, or type of work. Clusters exchange work on a regular basis - normally every two weeks - by posting it to a secure course and project management site at the University of Michigan. Participants then provide and receive feedback for members of their cluster. Having a deadline helps everyone get more done, and having feedback makes what's done better.
For more information, or for sign-up instructions, go to http://www-personal.umich.edu/~lpowner/workgroup.htm .
Any questions can be posted to here as a comment to share with everyone, or emailed via the webpage.
Last year some 20 people participated. It's a really nice opportunity to get feedback from people you don't already hear from regularly or who might bring very different perspectives to your work.
