Actually, I noticed that behaviour a few days ago. I find it a lot easier to express my ideas through images than words, so I'm changing my way of posting.
I usually take a LONG time to write something and after that I edit it a million times (maybe you can check that too), because I can never find the correct words for my thought. I can't even cite quotes correctly without google because I always mix the words.
My thoughts are like big blocks of ideas, so I have to break them in little parts for other people to understand.
I started writing this just after you posted the message above, and look at all the time I wasted on this process... Also writing stuff in the beginning then in the end then in the middle then in the end then coming back to the beginning again... ah...
But I pick images very very very easily, then I can express my idea without typing.
Anyway I suck at writing, more info

EDIT: and when I look at what I wrote, I feel weird, like it was done by someone else, because I can't remember what I was thinking at that moment just by looking at the text. If someone showed me anything I've written like 5 years ago, without saying it was me, I would certainly find it cool and ask who did that.
When I look at an image I posted (or a drawing I make, in real life), I see my idea there, like I was jumping back in time.
