Currently the question “Do you use any article organizers?” has three votes to close as off topic. However, in my opinion, this question can be interesting to people working on theoretical computer science and is not off topic, although it is not a question in TCS. At least I am interested in what other people in TCS use.
(As I wrote in a post to another discussion, I am a little bit tired of big-list questions, and this question may be one of them, but that is a separate story.)
Also, if you are a theoretical computer scientist looking for good citation organization software, I can imagine a reason for you to want to ask for recommendations of other theoretical computer scientists rather than researchers in other fields; it can be expected that they have similar requirements to you. In this sense, I can argue that the question is about TCS, although admittedly the relation is not strong.
Is this question on topic or off topic?
Added: The question has been closed as off topic. If that is the consensus of people here, I am fine with that, even though it was a little surprising to me because I had an impression that most people were happier with non-technical or broad questions than with technical, focused questions. Honestly speaking, I personally prefer technical, focused questions than highly-voted soft or broad questions, so I guess that I should feel happy to see that this question has been closed as off topic rather than feeling sad.
