Does this question belong on Stack Overflow or not?
Why or why not?
I think that for a great many of us, an HTML editor is a tool used in the development process. I think the important distinction here is that he isn't asking for help in installing such a tool (which would be a superuser question), but is asking for advice on selecting a good tool.
Since selection will critically depend on the fact that one is a programmer and not a hobbyist or heavy-hitting UI designer, this is definitely fair game for SO.
Asking about a program is not programming related. Even if you program with that program.
Asking how do you a certain type of code with a certain type of program. Is programming related.
Program program program.
What I mean is. Questions about using a program are on a gray line. There are questions about using a program that fit perfectly with SO and others that do not.
But questions about where to get, how to install etc are IMO not programming related.
To answer the original question, I think yours is on a gray line but it's worded well so IMO it's fine.
This comes down to the old question - is 'pure' HTML design (without automatic markup generation or scripting) programming related, or not?
Since HTML is a markup language, not a programming language, many people feel that designing HTML is not programming, and therefore does not belong on SO.
I disagree with Ólafur's answer. Of course, HTML isn't programming. But it is related (rather closely, in fact). Therefore in reply to his statement: Related related related
Edit In reply to Ólafur's update on his answer:
It didn't get closed, so the community apparently thinks it is a valid question.
My take: HTML editors are programming related, so it's a valid question.
Also the fact that 7103 posts on SO are marked with the html tag (at the time I post this..) means that html related questions definitely belongs here!
