No, they'll develop it into a real-world search engine.

For sexcoin, your proof of work is in form of a sperm probe?

You mean, those where you first have to move tons of material to get the ore (and in doing so not only consume energy, but also damage the environment), then to consume energy to transport it to the place where the ore can be converted to metal, a process which itself takes a lot of energy, then you have to transport the metal to the mint (consuming energy) where you have to again melt it to get it into the right portions, and finally you coin them, probably using a machine which again uses energy for operation?

SETICoin? However that would collapse the very moment extraterrestrial life is found. :-)

Who cares about the absolute value of any particular coin?

Anyopne speculating with them, I guess. And anyone using it as a payment system.

What matters is the ratio of its value to mining difficulty

That matters to miners. To others it only matters very little.

Third option: Your employer can simply decide not to be your employer (that is, not employ you, or fire you if you are already employed) unless you accept your payment in legal tender. And every court in the world would approve that.

Indeed, the best way to get rich with cryptocurrency is to create your own version, mine an initial amount for yourself, get enough people to join, and then sell yours before the bubble bursts. ;-)

Not every plane is an Airbus. ;-)

The news is that North Korea has an internet from which it can erase that information.

I've been looking for one?

How should we know if you have been looking for one?

Here's a hint for you: A question mark marks a sentence as question (therefore the name "question mark"). If it is not meant as a question, don't put a question mark at the end.

I know it's fun to bitch about corporate power, but corporations won't be shooting a pregnant wife in her own house (ruby ridge),

If there were not a government making sure that such an action would be punished, I'd not be sure about that. After all, illegal corporations (also known as organized crime) are known to have no qualms to do such things.

putting you in a cage for taking pictures,

They don't need to because they know they can just call a government agency to do it for them. Otherwise, see my previous point.

or forcibly taking everything you own because they decided they have the power.

Oh, they do so as much as they can (see statuatory copyright infringement). Also, see my first point.

Yes, sometimes documents are required in DOC format only. But fortunately in my experience that's rare (YMMV, of course). Quite often PDF is accepted as well.

It was more frequent in the past. That it no longer is probably is to a good part due to those people who just can't stop educating others about the problems of demanding (or passing around) DOC files.

Otherwise you're just manufacturing stress and effort when there doesn't need to be any.

Those people who demand DOC for no good reason are those who create unnecessary stress and effort where there does not need to be any. It's only fair if they get some of that back.

It's not as if reading PDFs would require installation of any non-widespread or expensive software, or would take a lot of effort in any other way.

So if it is named "Financial Crimes Enforcement Network", then obviously its aim is to enforce financial crimes. So, not only does it not fight crime, nor does it simply ignore crime, it isn't even just promoting crime, no, it enforces crime! :-)

What other offerings?

Windows Phone, and the Xbox operating system. ;-)

ODF, like DOC/DOCX is a format for editable documents. I consider neither appropriate for finished documents. Use PDF (ideally, PDF/A) for that.
