Backfence Inc. of Falls Church, which has launched online community forums on the premise that all politics -- and advertising dollars -- are local, has secured $3 million from two big out-of-town investors: Manhattan venture capital firm SAS Investors and Redwood City, Calif., investment group Omidyar Network.

"This funding allows us to rapidly roll out Backfence to create vibrant local online communities like the three we've already launched in the Washington, D.C., area," said Mark Potts, Backfence's executive vice president, in a written statement. Potts was formerly on the staff of The Washington Post.

For more than a year, Backfence.com has chronicled the not-in-my-back-yard fights, business openings and closings, and other happenings in the Fairfax County communities of McLean and Reston. The Web site recently crossed the Potomac to add Montgomery County's Bethesda to the mix.

The hyper-local site also received angel funding from local technology community glitterati Edward H. Bersoff, Frank A. Bonsal Jr. and John Burton.

The three were also named to the Backfence advisory board, along with William F. Allman, general manager of Choice Media Inc.; Merrill Brown, principal in the consulting firm MMB Media; and Michael Rogers, former editor of Newsweek.com.

Backfence chief executive Susan DeFife said that Backfence plans to expand to 16 metropolitan markets, with 10 community chat sites in each, over the next three years.
