Hey Tanvir,
I agree with you that blogging is a great form of demonstrating your learning result. It also allows you to see how others think. I also prefer using Twitter and YouTube for learning purposes. As you mentioned, hashtags are a useful tool for us to filter helpful sources. However, I also realized that some people are throwing various hashtags just for no reason. YouTube is another platform that I use the most for both educational and entertaining purposes. There are so many educational channels that helped me a lot. It is also interesting to read the comment and see others sharing some deeper or thoughtful understanding.
Nice post!
Thank you.
