I believe than helping smaller users, even if we are small as well is basic for this community and this project to succeed in the long term.

As more people come to join the platform, the amount of help and advises will necessarily increase accordingly, and older/bigger users are certainly not enough to help such a massive amount of people.

In my case, I belong to a new community called @promo-mentors which was founded by @futurethinker , and in there we offer several of the things you mentioned, like for example:

• Mentor someone or a community
• Provide instructions and guides

We have mentors that actively help users in making better posts. Mentorships are for several subjects, like science, poetry. We even have spanish speaking mentors to help that community.

• Boost others
• Spot the hard-working underdog

We also do this with what we call "Encouragement boost". Which is where our mentors put the best post of users who receive little reward, so we can give them our community vote.

So I believe what you say here is spot on, and should be applied by more and more people. That's the only way to have sustainable growth, and if everything goes well, this year should be one with explosive popularity for steem.

Cheers mate.
