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
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.
