I think SteemIt has done a fantastic job growth wise in the last year and a half. There is absolutely no doubt in my mind that in less than a year SteemIt is going to explode.
If the price of STEEM continues to rise and stays steady, many private bloggers will soon realize that it will be more profitable to blog on SteemIt than their own websites. I think that's when there will be a huge influx of new members.
All I know is that SteemIt is only going one way, and that's UP!
