P.P.S. Mr D should try using twitter more like Hugh Bonneville because according to the Telegraph, circa 2011, he rly knows how to do it:

Hugh Bonneville's simple pleasures

Few, if any, users of the Twitter social networking website make a better advertisement for married life than Hugh Bonneville, the Downton Abbey star.

The 47-year-old actor has lately regaled his 16,600 followers with his happy experiences at Chessington World of Adventures with his wife, Lulu, and nine-year-old son, Felix. It is the simple pleasures for Hugh: he talks, too, of his joy at "jogging through a bluebell wood... glorious."

His tip for wholesome television viewing for Easter Monday? Just William on CBBC. "It's superb family viewing," he decrees. The star not merely of Downton, but also of films such as Scenes of a Sexual Nature and Conspiracy of Silence, Bonneville has undoubtedly come a long way since he started out at the National and the RSC in productions of The School for Scandal and 'Tis Pity She's a Whore.
