Excellent analysis on all points.

Expanding on two areas (to help @pandev and others)...

1. Comments are important, and relevant comments can be very important.
   A common 'discovery' route we use when curating is by visiting the authors of the first one or two good comments on a post we have just visited.
   So comment more and comment well.

2. Content is King - but it should have value and it should have an audience.
   We like to reward 'content with a purpose' and even better 'content with an audience'.
   Who is going to read your content and what value are they going to get from it (be it information, education, entertainment, enjoyment)?
   And who is your audience? If your posts aren't attracting any audience you need to either build an audience for your content, or try different content.

For @pandev his choice of content is a weak point. Many of his posts (The step of Human, Stay Hopeful, Love...) are very generic, with no strong purpose or audience.

His recent post 'GMSA - UG KNOW YOUR EXECUTIVES' has value and purpose. He just needs to build an audience for this sort of content.

And there is still some work to do on writing style and presentation, but that is not too far off the mark.

One final general point that is critically important for everyone starting out on Steem - Visibility.

Get known, get seen, get read, get voted.

Hope all this helps, and thank you again for the very thorough and interesting analysis.
