With all the bot followers and comment bots, many people are not following back because they may not know if they are active members here. Upvoting is also important as some may not upvote but comment for the aim to earn a little upvote from author is a bit impolite. A little upvote is really a nice token of appreciate for one another. I will look forward for your new experiment when it is ready. No rush! Cheers for more interesting articles and music from you!
