finally, I'm super glad someone covered this problem. I've definitely been subconsciously thinking about it myself.
I have a potential partial solution for #Steemit - on the post listings, allow a preview of the post on the right side. For people with large monitors they can scroll through content, and hover over, read it and decide in an easier manner if it's valuable rather than having to open a new tab, read, decide, go back, or scroll and vote
Interesting idea.
