Wow. Seeing as they have 50 ish followers and I have 15000 ish followers, whick is 300 times them, then according to that I should charge 3btc each. That's about 15-20 dollars depending on what mood mtgox is in. Wow.
Saying that, I would never charge more than 0.5 btc
slight difference is that they have 50 followers which specifically decided to follow a bitcoin-related advertising account.
i.e. they have quality (not saying yours aren't quality leads, but they probably wouldn't have the same level of 'bitcoin' focus)
Oh yeah...
Didn't realise that
but then again, nobody said the tweets have to be about bitcoin...Maybe I could say that if your tweet is about bitcoin you get 15 percent off!(To promote the bitcoin system, or is that too complicated?)
You sir, shall get two tweets when I start aswell
