Facebook has scooped up another startup in its path toward mobile dominance. This time, it's Glancee, an ambient location-based service that competes with Highlight.

From Glancee's home page:

"We started Glancee in 2010 with the goal of bringing together the best of your physical and digital worlds. We wanted to make it easy to discover the hidden connections around you, and to meet interesting people. Since then Glancee has connected thousands of people, empowering serendipity and pioneering social discovery. "We are therefore very excited to announce that Facebook has acquired Glancee and that we have joined the team in Menlo Park to build great products for over 900 million Facebook users. We've had such a blast connecting people through Glancee, and we truly thank our users for being a part of the Glancee community."

Less than a month ago, Facebook acquired the mobile-based photo-sharing app Instagram for $1 billion, and the world's largest social network has expressed its sights are set on mobile.

Glancee fits the bill. It was one of the hot passive location startups at SXSW this year, along with Highlight and Sonar.

Facebook's just weeks away from an initial public offering. The company announced its shares would be priced at $28 to $35, putting the company at a valuation of $85 billion and $95 billion. Facebook did not disclose the terms of the Glancee acquisition.
