Faves.com is shutting down for good. The social bookmarking site, which was on its death bed before an infusion of cash revived it in 2009, has struggled over the last two years keep its doors open.

In a blog post yesterday, CEO Mike Koss and Faves' sole employee, said the company was not able to sustain the costs of operating the site.

Here's the bulk of the post:

We're shutting down the Faves.com service within a matter of days. If you want to export your data, please visit: http://faves.com/exportbookmarks.aspx

Unfortunately, we were not able to sustain the costs of operating Faves.com from our current revenue sources. We will be selling the remaining assets of the company shortly.

Faves (formerly known as Blue Dot Inc.) has had a roller-coaster ride over the years. Founded in 2004 by Mohit Srivastava and Sumit Sen, it started out as a social networking site backed by $1.7 million in funding. By 2008, the company was on life-support and forced to lay off the bulk of its employees.

A $75,000 angel investment from Geoff Entress in 2009 revived the company, which then repositioned itself as a social bookmarking site integrated with Facebook and Twitter, with Koss running the site solo. At the time, Koss said the cash infusion would be enough to sustain the company for two years while he built ad revenue and searched for other revenue models.

A little over two years later, it looks as though his efforts weren't enough to keep the site alive. I've reached out to Koss for comment.
