I have a Game of Thrones parody account on twitter with 38k real followers that are very active. We get a great amount of RTs for only 38k. We are currently growing at a rate of 200 followers/day for the past two months and GoT starts in April which will create a big boom for us. Should be at 50k in no time. To gain followers, I search GoT related tweets and favorite them and also just send out quality tweets. I'm not at all interested in selling the account, but was curious about the worth of twitter accounts. If the account were to get to 100k, what would the estimated value be? My eventual plan is to make a site with adsense and a few other ways, but that's not until I get bigger.
