Help picking an appropriate citing style I wrote a paper about governance mechanisms at StackExchange in which I got a lot of informations out of questions (especially on meta). I have kept all my references. 

My teacher is letting us pick which style we want to use for the paper as long as we apply it thoroughly. In my other courses, we use APA but if I start writing (StackExchange, 2014) everytime I use an info out of a question, my paper is going to be illegible. From what I've read, you're only supposed to cite things that you've paraphrased, ideas, not necessarily information that you've found or researched but I do want to give credit where it belongs and I would also like if my teacher would be able to retrace where I've found things but APA doesn't seem to include such a thing as a bibliography. 

I would like to:


have a bibliography at the end containing the documents I've consulted for my research
be able to have my citations as footnotes


Which style should I go for in this case?
Though I'm not a fan of it in general, in your case the IEEE style could work very well.  In the body of the paper, references are numbered in square brackets, like this: [1] and [2,3].  In the bibliography, you'd just have one entry per web page, with the URL.  If you use LaTex, it's easy to make these all active hyper links, so that your professor can click on the "[1]" to go to the bibliography entry, and then click on the URL to go to the StackExchange web page.  It's also possible to make the references hyperlinked in MS Word, but it might take some manual formatting steps to link each reference to each bibliography entry.
