The streamers that were chosen are those with strong ties to the community that the devs have interacted with before. It was not a choice based on size or how much they play Terraria.
Well they would have seen, if they decided to stop by, that a couple of us "lowly trying to make it in the streamer world" small guys are pretty good with our viewers and have a good grouping going. TheVideoGameBadger, RiffRaffGames, and myself Tohclan have all been working hard and getting a good viewer base going.
