I’m afraid to write blogs

I’m not so good at titles, also.
So maybe I’m afraid to waste people’s time, because I’m not sure if they will find anything useful. And everything should be useful, even if not for material profit, then for fun, isn’t it? For the great future, we should spend time as effective as possible to gain production per time per person ratio.

From the other hand, people are so much likely to shit-talk [Medium is a good example], why am I worse than them?
