Who is worth of following on social media to enrich marketing and business knowledge?

On Twitter, it is classic – many of us follow YCombinator people, Angel Investors, or big indie makers.

The most popular are:

• Garry Tan

• Levelsio

• Marc Andreessen

• Marc Lou

• Michael Seibel

• Naval

Do you know any other person worth following because of their good takes on entrepreneurship and practical pieces of advice? It can be smaller accounts, too.

[P.S.: I do not know why it shows that US flag, I just copied some Twitter link. But I can frame it like: Happy Thanksgiving day.]
