Depends heavily on which border, I think. I live in eastern Austria and don't know any Czech, Slovak or Hungarian despite those countries being within an hour's drive of where I live. For the most part I expect people in Austria to speak German, I don't expect people even in border villages of Czechia, Slovakia or Hungary to speak German; if they do, that is a nice surprise.

Some years ago, in a border village in one of these countries, a child spoke to me in the local language; I tried speaking in German and English, but the child didn't understand either, I could barely say "I don't speak (your language)" in that language. Eventually I figured out he was trying to ask me how old I was, and I could show that on my fingers...

I think that mainly mocks the idea that if only people talked to each other more, communicated with each other more, tried to see things from the others' perspective, then everything would be great and everyone would arrive at a common conclusion.

You are right that if your car isn't level (especially if you want to move uphill), the process is somewhat more challenging and you need to be careful not to roll down the hill, but I have never been taught to use the handbrake even in those situations and have not ever done it that way (for context, I live in Austria, i.e. I have driven a manual transmission car on mountainous roads many times by now).

I am not familiar with the ones you mention. I do however suggest you read this: https://slatestarcodex.com/2017/05/01/neutral-vs-conservative-the-eternal-struggle/

Especially the part you find if you search for "Voat" on that page.

Of course they are not equally good, no question about it. They are still both (technically) open standards and the main point is that they are both supported by both pieces of software, i.e. the practical difference between them is mainly in the UI, you don't need to get the other one just to read files created by one of them.

I didn't think I needed "protection" from anything on the Internet at all when I was a minor.

My stance has not changed merely because I am no longer personally affected. I still think that it is completely stupid to want to keep any information at all from young people in the first place.

As opposed to all your base, which are belong to us. SCNR

historically a "PC" is a machine compatible with the "IBM PC" and the only OS available for that was DOS or later Windows

Of course then Unix-like operating systems started to become available for the same machines, and Apple switched to Intel processors for a while too.

I don't disagree with that at all. But better that it runs in the browser's sandbox than that you have to install it to your machine which would work only under certain OS.

I read that when YouTube was new and just getting popular, the owner of utube.com got lots of problems with server load.
