There should be a feature coming out soon that will allow for community type platforms similar to /fa/ etc. Unsure when this will be implemented, but it should be "soon".

This platform is a good combo of anonymous and real personality - choose whatever works best fro you, some people like to follow a "person" it creates some layer of trust in my honest opinion.

Low effort posts that are genuine are better then low effort posts that are malicious. As long as you aren't manipulating/spamming most people will let it slide, medium-high effort is encouraged but at the end of the day the market will process the post how it will.

I'm not sure what you mean by signing your name, could you expand on that?

Also welcome to steemit :) wish you well while your here!
