Trying to convince people who already "know" is pointless. My prediction if someone tries is a whole bunch of trolling, cursing, name calling, and eventually the thread gets locked and nobody (on either side) changed the opinion of anyone else in the thread.
Not to mention get pretty high on Google. If there's one thing to keep in mind, it's this: the more responses a thread gets, the better Google rank it will have, especially if it's on a major site. The last thing we want to do is is promote a thread that's negative towards Bitcoin.
