The bad news — starting around 5 pm tonight, we have to close WSB to new comments for a few hours, to facilitate some tech-upgrade work. The good news — if all goes well (cross your fingers), that work should take care of problems that have caused the site to load slowly for some people at some times, including us (meaning that sometimes it takes us a lot longer to publish something than it should), and it also should pave the way for more new features in the works, so that WSB can better serve you. But comment away for now … we’ll let you know when the PEOPLE AT WORK sign has to go up; just wanted to give you advance warning.
