Welcome Yahwa here, very good Introduction post. Indonesia seems great. I am glad you found out about Hive through Twitter. It was same thing for me and later I found out my wife was also in Hive two years ago. What a world we are living, now I am kinda addicted to this awesome social media. And I am enjoying it. Welcome here. Keep it up. You will enjoy a lot here. Thanks
