I went with the first option, "After the show, someone who recorded it should start a vine". This way the person recording the show can tell if the copy they have is worthy to share. Too much can go wrong when a show is being recorded. It would be a shame is a thread was started and a decent copy couldn't be shared. Granted there are a few people that openly record shows. I'm sure there are a few that do it quietly as well. This may or may not be an issue, who knows.
I feel that the show should not be offered before its known that it is a good recording...There are a few times when I record off of Sirius where I get nasty drop outs for long enough period of time that I stop recording....I know not everyone has this problem...but just say I offered a vine of a show that didnt come out good....And then say there is a list of 20 people signed up for the vine....honestly if its not good quality I would not vine it....Thats why I feel I list should be started when we KNOW we have a good quality copy out there
