As Twitter users are generally in 'information seeking mode' as opposed to 'buying mode', I've found that Adsense has been by far my best money earner. Things such as affiliate sales, hasn't worked very well at all, however I can't say I've really tested this to the limit. It's been limited by a few CPA offers and Amazon. Just opening up to suggestions from you guys (perhaps from your own experience) to what you think could work well with Twitter traffic. I do have a lot of followers (over 1 million), so looking to start something which doesn't rely on Adsense (chickens & eggs).
