I have most definitely noticed the rise in quality comments on my posts. It is quite refreshing to have actual conversations about my content! I have been on steem for 2 years now, and can note that the platform goes in waves, as far as popularity and price. I can say that the price fluctuations have been drastic, but there has always been higher highs and higher lows. Now is the time to accumulate, grow, and enjoy the platform.
