This is the last day on the job for Rebecca A. Cooper, the Arlington community reporter for Rosslyn-based TBD.com.

Cooper joined TBD last July, a month before the site launched. She was formerly a contributor to DCist.com and a reporter for a Long Island newspaper. No word yet on her future plans.

TBD is in the midst of layoffs and will likely not replace Cooper or her Arlington coverage.

The layoffs are part of a reorganization that will shift TBD’s mission from being a primarily news-oriented site to exclusively arts and entertainment-oriented site.

TBD’s corporate sister, television station WJLA (ABC 7), will eventually relaunch WJLA.com as a separate, news-oriented web site. (WJLA.com was replaced by TBD after its launch.)

On a personal note, it was a pleasure working alongside Rebecca, who was a total pro and brought an unrivaled depth to her Arlington reporting. Whatever she does next, we hope she stays here in Imperfect Arlington.
