LoL, I'm not saying it's wrong to try. But.... Lemme put it this way.. You have... a seven year old, and he decides he wants to get a parked 18 wheeler out of his way. Should he try pushing it?
Other analogy, a huge sailboat, and there's no wind. Should all of the sailors blow into the sail to get the thing moving?
You write a petition, and you get a thousand people to sign it, and you send it to the studio. Some intern is gonna open it, and take it to someone that is somewhat important. The somewhat important person will laugh in his face the second he hears it is a petition without even caring what it is about. He will then tell the intern to throw it away and send a generic "Thank You for Your Interest in the show" letter back.
Now, they'll get that generic letter back as an acknowledgement of their effort, so that they know that they accomplished absolutely nothing. In the case of an internet petition, you won't even get that, no one will read it, no one will care.
Ask someone that knows stuff about the Biz what execs think of online petitions. Ask JoeDM. He'll tell you that no one cares. Ask JMS LoL, he won't even care enough to read it much less reply, that should give you an indication of how things work. Hell, not even Vanilla Ice would reply, and he's a nobody now.
