What exactly does this section mean?
Does this only specifically apply to complete timelines (i.e. if I am pulling a complete timeline onto a webpage), or is it ANY case where you have more than a single tweet on a page (even if those tweets are separated)? What about mixing odd tweets with odd Facebook posts on a single webpage?
I understand that you likely don’t want Facebook posts mixed directly into a timeline, but what about physically separated comments pertaining to a single topic on one page, containing both tweets and FB posts?
