I have been a fan of the SETI@home project for a number of years. I was sad to hear that the project is going into "hibernation".
UC Berkeley has announced that the volunteer computing part of SETI@home will stop distributing work and go into hibernation on March 31. Two reasons were cited for this action:
1) Scientifically, they have reached point of diminishing returns; basically, they analyzed all the data they need for now.
2) Managing the distributed processing of data is labor intensive. The priority now is to focus on completing the back-end analysis of the results they already have, and writing this up in a scientific journal paper.
It’s important to note that SETI@home is not disappearing. The web site and message boards will continue to operate.
