I sometimes see questions asking for the "best" software to solve a particular problem. Usually I have no hesitation closing these as "not constructive" as they rarely add value to the site. If the software is ubiquitous, there are usually any number of people willing to weigh in - and typically there are existing sites that already encapsulate reviews of said software. For example, the "best IDE", the "best AJAX file uploader," are not adding much value to the internet.
Recently, though, I came across such a question (see below) that was narrow enough that it seemed likely that there were few if any resources that might be devoted to compiling a list of the available options. It made me wonder if there might be exceptions to the rule where a question asking for a simple list of available options with recommendations might not be acceptable. I'd argue that any question that asks for "best" is simply begging for an argument, but one asking for a compendium of options might be acceptable. For the example below, I edited and tried to recast it as such a question?
Your thoughts? Should it or similar, narrowly-focused/lower popularity "give me some options"-type questions be allowed to remain open?
