I recently decided that it is time to shut down WP Lookout, and today I publicized an announcement about that and sent out notice to my users. I have a full "shutdown checklist" that I'll be working on over the next month. The announcement post summarizes my reasoning, basically that it's not providing enough value to enough people to justify the (relatively small but non-zero) time and expense involved. It's been a great experience and I'm so glad I built and launched WP Lookout. Now, on to other things!
