CBS filmed at 221BCon last April. The footage finally got aired - and then instantly hit YouTube (

Some of the Sherlockians I know think it had a certain supercilious air; I've seen so much coverage of SF fans as overweight, inarticulate, porn-riddled saddos that I thought it was quite reasonable. Heavy on Elementary, but that's to be expected from CBS; gotta root for the home team.
Was very started to see myself in the background of one of the interviews, along with another Benfester.
