Microsoft has closed down its ThumbTack service for bookmarking: The service at Live Labs let you save all manner of things, including links and photos, in a single place for later retrieval or viewing. Because this was a "lab" experiment, nothing was guaranteed. If you go to the ThumbTack site today, it still encourages you to sign up--and directs you to a dead site

O happy day, here at itdied.com: The tr.im URL shortener service has opted to stay alive instead of shutdown. Shortcut services have a hard time making money because their job is to stay out of the way. After a flood of "how can we help" messages from users, tr.im's parent firm, Nambu Network, is moving the service into a community-operated mode, details to follow. The company will transfer the domain name, databases, and software, and hopes that it can be run via donations and other means. The CEO of Nambu will pay all expenses out of his pocket until funding can be worked out.

Microsoft is shutting down its Soapbox video service that no one knew existed: Soapbox allowed users to upload videos, which appeared on MSN Video, a service that will remain, but which doesn't (seemingly) allow amateur/personal contributions.

Soapbox will stop allowing uploads on 29-July, and shut down entirely on 31-August.

The Yahoo 360° social networking blog thing, which has been under a death watch for two years, finally dives 13-July-2009: The service is notable for combining blogging and a host of other things, but Yahoo couldn't either figure out how to capitalize it or develop a new service to move content to, despite such a general promise two years ago. Now the service is slated to shut down, and you can migrate any remaining content out. (Thanks, Aristotle!)
