Very interesting - do you mean to say that people watching for new tweets came across that tweet and the whole thing just took off? Or, did you publicize it on other mediums like FB too?
In my case, the hashtag was all I used. McCain's "That one" moment was enough of an insta-meme that it exploded pretty quickly.
I think the key was spotting that the phrase would resonate with so many people as soon as he said it. By the time the press picked up on it and columnists started writing about it, I had already made the bulk of my sales, and the dropoff was as fast as the spike had been.
