I use Twitter to primarily promote and talk about work related topics – Eclipse, Commerce, Java, Dojo, etc and have noticed I get 1-3 new followers a day but I also noticed my followers count never really grew much. So either these were people who followed me and then stopped following me or I was also losing followers at the same rate.
Welcome Tweet Effect.
Tweet Effect let’s you see when people follow and stop following you. You don’t get Twitter Id’s but you do get to see what Tweets win and lose followers. Check it out, the data is pretty interesting.
