Is it appropriate to acknowledge StackExchange in my MSc thesis? So, I'm just now finishing my master's thesis. When thinking about who helped me aside from my official supervisors some of the StackExchange fora (especially Stack Overflow and TeX) came into my mind. 
I asked some questions in these fora but most of the time I was just looking for information in older posts (and finding it most of the time). Now one the one hand it feels weird to me to acknowledge a site I browsed to, e.g., find out a certain programming command (like I would not really think about acknowledging Wikipedia). But on the other hand I am really grateful for some of the quick and professional answers I got from StackExchange users.

So what do you think, should I acknowledge StackExchange in my thesis?
Your acknowledgement is a place where you are free to thank anyone or anything (I have seen dogs being thanked) you think deserve mentioning. To acknowledge StackExchange is highly appropriate since it is a community driven open site where help can be obtained to solve problems from many different perspectives.

In my PhD thesis, I, perhaps a bit over-ambitiously, thanked Donald Knuth for creating TeX. Had StackExchange been in existence back then, some of the terror of writing my thesis in plain TeX would have been eased and it would have been placed along-side Knuth in the acknowledgement.
