After writing this weblog since July 2005, I have decided to retire it. It has been a very effective venue to present a wider range of viewpoints than were typically available elsewhere during the earlier period of my posts. In recent years, of course, a range of excellent weblogs that serve this purpose have appeared [e.g. see the long list of weblogs (cataloged by their different perspectives) at the right hand side of Watts Up with That. Most of them also permit Comments, which I stopped doing several years ago.
I want to spend more of my time on research papers. The time I have been using to prepare the weblog posts can now be used effectively on peer-reviewed research papers. I also am completing the third edition of my modeling book, which will require significant time.
The past weblog posts will remain on-line for the indefinite future. I very much appreciate all of the excellent input from the readers of my weblog! I plan to continue to publish and will be using that venue to present my views.
With Best Wishes to All of You!
