I totally agree with you @patelincho.
I have been around for about 4 months now, but i noticed this behavior already a few weeks back. Things like follow for a follow is not an exception anymore. I have the feeling that, just like you are saying, the new people think that Steemit is about earning money instead of what it is really meant to be; people sharing things they like, share their feelings, their hobbies and get rewarded for that.
I try to ignore the steemians that come and ask for a follow for a follow. I follow who I like and the ones I think have to give something good, funny, and sense to the platform.
Is not what Steem can give you is what what you give to Steemit !
