No, I’m not going to do that to the whole post. But I just noticed that, when I read upside down, I more notice that I’m reading backwards, and it takes me a bit to realize that I could flip it around and read it forwards.
Yes, it’s M & P, but it’s a poll, so I thought I’d put it here.
Finally, I’ve found a good use for Control+Alt+Down Arrow.
I chose the first option because I can, easily. However, either that font sucks balls or I need new glasses because it’s very blurry. Maybe it’s my boyfriend’s monitor. I’m not used to his.
Pretty easily. I had the habit as a kid of reading my books upside down during class, which caused my teachers to think I was just goofing off. Quite a few times I had to read aloud with my book upside to prove that I could, and was, reading that way.
As an economics teacher, I’ve learned to draw and label all the major economic models upside down, across a desk when tutoring. Compared to that, reading upside down is nothing.
I have to sit there and interpret it but I can do it.
Flashback to fourth grade. Our teacher was giving us a lesson with the help of overhead foils, and she was sitting next to my desk. The answer to a question she threw out was on the next slide, so I blurted it out without thinking. She looked at me and said: "You read that upside down and backwards." I guess I did. I never thought about it until then. I just did it.
I spent a lot of time in the principal’s office in high school. Reading upside down is a skill one acquires at such times. I’ve kept it up since because you never know when you’ll be able to use it and there’s no time to learn on the fly.
Cute!
My niece’s teacher told her parents that when she comes to a scary book she reads it backwards so it’s less scary!
I’m good at reading and writing upside down because I’m an English language teacher and often model handwriting or spellings for kids from the other side of their tables.

I chose the first option. I’m a teacher. Even if I hadn’t already been able to do so, I’d have been a fool not to practise until I could.
Pretty well but not quite as fluidly as right side up.
After I’ve seen that it’s upside down I can very nearly read it as well as if it were upside up.
Ah, but can you type upside down? 
My upside-down reading is slower than my upright reading, but it’s still faster than most peoples’ upright reading. I’ve never made an effort to cultivate the skill, but it does come in handy when teaching, as others have mentioned.
I have no problem reading upside-down . . . or even reading the label on an LP while it’s rotating.
I do well reading it when the type is normal, but I notice that in the poll the ‘g’ and ‘h’ in right are aligned oddly compared to how the would be on a sheet up paper turned upsidedown.
It’s really not that hard with a bit of practice
There’s a website that converts the text. The ‘upside-down’ letters are mostly extended Latin characters that are used in things like IPA, so they don’t necessarily align the same. Plus there are a few from other scripts (the upside-down g is some kind of Cyrillic letter, I think).
Ah, I was wondering how the heck you did that.
