Steemit discovery journey (1)steemit发现之旅（1）

When I was visiting steemit, I found something in the East. But I didn't know what to do. I would like to read a big God or a big whale. Here are links https://steem.global and screenshots.
刚才在逛steemit的时候发现了一个东东，但是不知道做什么用的，还请哪位大神或者大鲸鱼解读一下，以下是链接https://steem.global和截图:

The great God who can read about, thanked!
哪位大神可以解读一下，在此谢过了！
