Hi @trang. Yes, this is very helpful info. I have followed you, and also followed you from my three Twitter accounts, and will mention you in my gaming related tweets and Steemit posts. It appears you are Vietnamese. I currently reside in Vietnam. If you need any free advice on how to expand the reach of the SM videocast let me know. Transcription is (obviously) one of my focuses, and I am willing to work for some JUICY cards (ex. bonus packs or individual cards of preference). Industry standard is that it takes ONE HOUR to properly transcribe 15 minutes of audio/video, and the text which comes out of that will significantly boost SEO. Just consider this and let me know if you need assistance...
