I personally don't know Gregg Tavares, but I empathize with him. I also have answered hundreds of questions via tech communities but most of questioners do not thank me and they do not respond to my answers at all. I do not know whether they checked my solution or not. But I can keep this job as a hobby for many years because I do not expect that questioners thank me at all. I just do it for myself. Actually I do not think that I am helping people online. I consider myself that I am doing this just for fun. I can learn some lessons even from the silly questions written by the ignorant who do not have any background knowledge. I also have my answering history and I can use it for self promotion when I introduce myself to others. I even participate in developing some open source projects, but I also do not expect that somebody who like my code offer me a great job or help me improve my code. No one will give me a food on the table. No devotion, no pain. I just do something online that is fun for me, meaningful and additionally helpful to others.
