Earlier today we saw https://softwareengineering.stackexchange.com/questions/80898/how-do-you-ask-or-get-asked-to-speak-at-a-software-conference asked and subsequently closed as "not a real question".
It's gathered 2 reopen votes already and I personally believe it deserves to be reopened.
Looking at the highest voted answer in this question here on Meta, I think the question fits most of the criteria:
Is it interesting to programmers in general?
I think so, provided they're the type of programmers who want to speak at a conference.
Would answers be significantly different without "for programmers" added?
Some answers would be more general, but I think there are enough development-specific things that could be pulled in.
While it is true that other professions have conferences, I doubt, for example, that a speaker at an economics conference has to attend a local user group or create an open source project to become more known in their field.
Does the addition of "for programmers" seem like more than just an afterthought?
"Software" was edited into the question by request, but I don't think it's unreasonable to say that a question about conferences on a programming-themed site is about software conferences and not, say, knitting.
Will the question produce useful and/or interesting discussion?
I think so. I think many developers are focused on their own jobs and daily tasks and might think that speaking at a conference is for other people. They might not consider the fact that they, too, have a lot to offer to the community and that presenting doesn't have to be intimidating or only done by the big names in the industry.
Does this question make the internet better?
See above, I think so. As a developer, reading the answers given to that question, I could also extrapolate beyond conferences and see how I could improve the soft side of my career in addition to eventually improving technical skills.
I think the question could be expanded a bit to include something like asking what sort of preparation (at the technical level) is required for presenting at a software conference, but even as it is now, I think it should be reopened.
