You need to practice more in making your ad hominems more subtle and try to provide at least some actual reasoning for the things you claim, and if you're going to call people stupid you can at least try to do so by referring to things they actually said.
Anyway, what your users want is a program that they can figure out how to use, and one that they actually can get on their computer, and that does the things they need them for - all of which have absolutely nothing to do with whether you used a quick sort or a bubble sort. Being fast, solving "hard problems" (methinks you're a bit full of yourself - when was the last time you heard someone say 'man, if only I had software that would solve a hard problem'?), and being maintainable are all secondary to the actual use - i.e. having a user interface they can understand, provide output in terms they understand, etc.
In your second paragraph you are actually making my point for me, but you don't seem to realize. What users want is a program that does something for them, like extracting links - and they don't care if those links are stored in a linked list or array. Maybe in some cases they will care at some point in the future that, when they download 10's of thousands of links, that happens a few seconds faster in some cases than in others, but that's not their main concern.
