Oh, here's a good one. When someone's trying to sound like they did some actual research about a topic, and they go, "On the internet, it said..."
on the internet?! What website? Often when I ask these questions, they either don't know or just restate, "On the internet." Seriously, people, that's like saying that you opened up your browser and were automatically presented with the information you just relayed, and that there was nothing
elsewhere on the internet to conflict with that information!
I don't mind if someone says they can't remember the website (especially if they manage to look it up later and tell me what it was), but is it really
so hard to understand that the internet isn't exactly a single stand-alone program with information dumped into it by the cosmos?
