Karen Hall, sister of Joan of Arcadia creator, Barbara Hall, notes on her blog that there is still a remote chance that Joan could be saved. She writes...
...everyone should stop bugging CBS and start writing to Sony, who is shopping the show to other networks. Also wouldn't be a bad idea to write to other networks to encourage them to buy the show. Try NBC, ABC and Fox. UPN is owned by CBS, and the actors probably wouldn't be interested there anyway, or anywhere else that doesn't really have an audience.
There is a very real deadline of June 15th, when the actors' contracts are up. It's pretty much dead after that. So if you really want to keep the show around, you'd better start bugging your friends and relatives to write to Sony NOW. They can use the volume of letters when they are trying to sell the show.
