Personally, I am not looking for a site where I have to deal with people making comments such as "source?"

This is irritating to the nth degree to me. While I think it's important to back up facts if you are giving them, simply saying "source?" is one of the laziest and irritating things I see online.

Not everything has a source for one thing, I don't need peer reviewed papers to tell me that toilet paper in my bathroom is white.

For another thing, I've noticed this HORRIBLE trend where people will post things with lines like:

source: "I ate burritos last night"

That is NOT EVEN a source! If I were to write a paper on how I've discovered a magentic monopole, submit it to Physical Review A, and say source: "I once lived in Alaska, there are magnetic monopoles up there", they wouldn't even laugh at me, it's in the realm of Not Even Wrong

The whole questioning for sources online gets me really angry. I've seen arguments turn into "Who ever can find the most papers on a subject wins". It's ridiculous and one of the many reasons I am glad for hubski.
