RE: How does all this work?

1. Welcome to your blog :)
2. PeakD, like HIVE, splits posts into different communities which can be thought of as Sub-Reddits, Facebook Groups, or Old School Forums.
3. Ask people. This place isn't an echo chamber; despite what you might think.
4. If you see something on someone's article and you wonder how they did it, ask.

Enjoy your time here :)
