Does this question belong on Stack Overflow or not?
Why or why not?
Questions about best practices and other aspects of programming, including use of software tools used in the development process, standards for maintenance and readability of code, advice to avoid potential coding pitfalls, etc.
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.
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.
OTOH, I believe that any web developer worth his salt will want to look up the HTML source his code generates from time to time. From this perspective, HTML editors are programming related.
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:
He is right in saying that there is a gray line, and I agree that a question like How do I install Visual Studio does not belong on SO. Even though installing VS is certainly programming related, such a question is better placed on SU.
The main reason why there still are such questions on SO is that they were asked before SU was available. That can not be used as a justification to post such questions on SO nowadays.
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.
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!
