If you want to build a decent twitter account with a variety of followers, is to change your twitter username every time there is a major news event happening. As an example, when the pope was getting announced, there was a bunch of accounts that were of the seagull on the top of the Vatican, i just changed my username and pic, and started posting stuff about that event, loads of new motivated followers. After a couple of quiet days, i had another idea, and just changed it to that. Keep re-using ones that are popular every few weeks. Once you start to identify a niche give them the relevant offers, and expect good results. My newest one is now a female, and its great for clothes website affiliate offers.
