Xmarks, the popular browser bookmark synchronization service, is shutting down on January 10, 2011. Xmarks is a free service that saves your bookmarks across different browsers and different computers, and currently boasts about two million users.
"The synchronization service continues operating quietly, the servers chugging along syncing browser data for our 2 million users across their 5 million desktops. The day isn't over yet, but we're on track to add just under 3000 new accounts today.
Tomorrow, however, will hardly be anything but typical, for tomorrow one of our engineers will start a script that will email each of our users to notify them that we'll be ceasing operations in around 90 days," Todd Agulnick said in a blog post.
Xmarks is, to a large degree, more like a Yahoo Directory or a DMOZ than like a true search engine; it's a huge database of web sites and web pages bookmarked by its users. And the current "bookmark search" tool it offers is quite good.
