Congratulations on your first post. As for its content, i largely agree with you, though there are other pathways towards being a credible, trustworthy and reputable voice.

Many of the facets you have listed are in some way connected by passing on knowledge, best practice or current trends in a meaningful and honest way. I certainly believe this is one route to the above.

However, you did not mention the type of individuals that shape the ecosystem. Leaders have authority (though not necessarily trust), trailblazers that make their mark (being founders or disruptors) in a field will have a reputation and genuine challengers of the status quo do as well. Key there is for them to be right (as in: correctly anticipating a change in the market, field or trend).

Again, bravo, great post. Looking forward to more!

There is little question, however, that the type of figures I mention, will have to practice or have the attributes you mention.
