Once again it is a confirmation of the popularity of Steem, when shortly after your posting the number of comments shooting up and it is clearly visible who is waiting for every single post, both constructive comments and just spamming but this is a live there will be always pro and contra. Important thing we should not let the people who want to rebuild Steem and Steemit to be distracted by negativity and just ignore them.

As to mentoring it is a great idea and reading through the comments bellow we can see that many people already doing that. When newcomers post their first post should receive a “welcome” comment that would offer to visit mentoring post or page. The mentoring page should contain basic info and offering different types or fields such as game, travel, photography, writing, art, homesteading…

Each section then should include those volunteers who would like to be mentors and who the people can reach in discord, there should be discord page too.
Issuing posts throughout the process of establishment with appropriate rewards for both parties is great idea too, will help newbees to be visible and reward mentors for their work and time.

In general it is time consuming if someone want to do a good job that is why the selection of mentors should be really strict if you want it to work properly.
