How many are we in the world ?

MSX Users that uses real MSX? With me we are two

@ wernerkai: What do you mean? What did they say? Can you describe it, quote it or post screenshots?

As to your question, it's interesting. I have no idea. It also depends what you mean with "real MSX users". I suppose you don't mean all those people who get nostalgic feelings when they see Knightmare; the "once weres". Maybe you mean the people who actually own a real MSX and still use it sometimes. But I'll go out on a limb and assume you mean those who are still interested in playing the old games but also new ones, even if it's 'just' emulation, and are following the news about MSX.
If I can gamble on that last category, I'd say about 10.000 people worldwide is a pretty safe and accurate estimation. But I could just as well be very wrong.

But these trolls, sorry to bring it up again but I'm somewhat interested, was it actually a discussion about MSX and/or its relevancy?

I know that here in The Netherlands, there are still a lot of poor, lonely MSX machines collecting dust and cobwebs in attics of houses and probably schools as well. Among MSX owners in NL, there are possibly more people that half-forgot actually owning one as opposed to actively using it.

I think real MSX users are people who at least still follow the news on this site on regular basis And then there are the die-hards, who still bother to contribute to this system in any kind of way, like releasing software, add pictures and games to generation-msx, attent fairs ect. I don't think there are still users out there who write their letters in tassword and print it on fanfold paper

Sticking to a literal definition... A real MSX user is a person who uses an MSX machine. That simple

And I am one of those
