Spool, a mobile social bookmarking company have been acquired by social networking giant, Facebook. The Spool team informed their users via the company's blog, announcing that they were joining forces with Facebook.

Facebook won't be bringing any of the Spool name to their services just yet, with the Spool service shutting down, and the company also send out e-mails to Spool users this afternoon informing them how to move their bookmarks to another service.

It was only earlier this year that Spool raised $1 million in funding from SV Angel, Felicis Ventures, Charles River Ventures, Vivi Nevo and other funders. The company was founded in 2010 by a former Google product manager.
