I have carefully read @skapaneas post and I have found out many interesting ideas included.
Steemit is after-all a (still new) social media platform and since most of the greater social media networks can be integrated, why not steemit too?

For instance at the moment a user can connect their twitter account with facebook, and anything posted in one of them, is simultaneously posted in the second. Instagram can be intergrated with a variety of platforms and there are applications such as iftt that can connect multiple channels at once.
Even though I do not agree with delegating SP for doing it, it is a thought that can be examined and with some technical help, it can be determined what are the possibilities and/or enhancements!

On the other hand (complementary to the above thought and not excluding it), I also like the idea of @onceuponatime and I believe that everyone of us has tried to do it to some extent.

People like to share useful knowledge, are happy to review online and rate/criticize products, services (or even people)

I am not sure of 'pledging' though. In order to 'educate' someone, you need to have sufficient knowledge. Otherwise you might have a reverse effect.

People who can do it (educate other people), do it anyways and many of them (even without knowing it) have helped many newbies (including me).

It always comes down to us in the end..
