there is a little icon (it's there for comment posting as well) at the far right that looks kinda like a movie projector (at least, i think that's what it's supposed to be) when you hover over it, it says insert media. you click that and select the option on the top far right: from another website. then, a box will pop up. you copy and paste the link of the tweet or instagram post in the box, and click insert.
