The above headline is what you call "link bait." Furthermore, it's completely misleading. Not only because I'm not going to show you how to raise millions through Twitter, but because there really isn't any known way to raise millions through Twitter -- other than getting very lucky. Link bait works because it attracts people to new, faddish, cool things.
Twitter is a shiny object. It's easy to get people to look at it, even obsess about it. And while there are perfectly good uses for Twitter -- and maybe even funds to be raised -- you (yes, specifically you) are going to make a lot more progress by looking more at the unshiny object.
See this great post at the Infomarketing blog: Beware Of The 'Shiny Objects'.
Ignore the shiny objects and instead hone your core direct marketing and advertising skills. Because every productive minute you spend today doing this can pay dividends for years to come.
Concentrate on the proven stuff. That's how you'll find yourself in the position to use the shiny objects.
