There are a lot of people here mentioning in their comments " I am upvoting you, please upvote me back" or leaving their link there. It is very nonsense. If you share meaningful or useful or interesting things, you don't need to ask or even beg people to follow or upvote you. These things are not serving the aim of this portal. About upvoting from my side, I am upvoting or commenting every article I read, because I am reading only the articles I find them worth to read like yours ;)
