I here ya.  It is a little disconcerting when two-thirds of the post on the main page are all about Steemit.  BUT (and this is a big but), I've been here for about a month and I have to say that my favorites posts are usually about...you guessed it...Steemit.  Why?  Because this thing is both addicting and different.  It's like nothing that has ever existed before.  It's taken me a month of reading to just begin to get my mind around it.  And, contrary to your suggestion, I think there's a lot of noobs here who are EXACTLY like me in that regard.  They want to read and learn about Steemit.  To some degree, the more we feed that beast the better.  

Having said that, I do go out of my way to vote up unrelated content, and I think all dolphins and whales need to make a concerted effort to do the same.
