Thank you @anotherjoe. When I first came to #Steemit, I operated in the same manner that you mentioned. I had a two week break of madness IRL that I had to deal with and when I came back I realized that I need to expand my sights and have been consciously seeking new authors of good content. Like yourself, I too upvote only on those articles which I have read and appreciate, and I do my best to comment on the ones I upvote as well - though sometimes the content is not of such that I have a vast knowledge on, or cannot fully wrap my head around, and have nothing to say other than "Great article, thanks!" (hahaha) so I just stay silent.
