Vox Populi Forum
They generally research things pretty well, although he can sometimes be myopic. The episode on why bidets are not popular in the U.S. went into historical plumbing conventions without considering things like the average American showers a lot more. Still pretty good, well researched, and generally fairly interesting. Part of my standard lunch time youtube viewing.
