You are absolutely right - I try to promote Steem in some communities I am engaged in, because I think so called warm acquisition is more effective than cold acquisition...

Anyway, this was one of the first issues I mentioned as a newbie in steemit, that there is not much promotion outside...

Maybe because of still beta or people think they found a gem which they don't want to share...

That is quiet comprehensibly to some extend - but I guess in the end we all will just profit of a growing community...

I did this quiet in the beginning of my career here on Steemit ;)
