JS a newsman? That's funnier than JS on his funniest night -- you're quite a comedian, perhaps you should apply for Jon's job.
Even when Jon Stewart is telling the truth, he cherry picks facts that support both his worldview and that he can spin a gag around. And, for a political comedy show, that's completely appropriate. The problem is, too many people seem to think the Daily Show is a news show just as too many people think any 'fact' Rush Limbaugh states should be considered to be anything but fiction until carefully investigated.
The Daily Show is a comedy show built around a few selected memes that are floating around that day or week. Jon delivers them well and is funny if you can stomach the complete lack of balance and the lack of "truth, the whole truth and nothing but the truth".
I stopped watching him because I eventually got too annoyed by his complete misrepresentation (or, perhaps a misunderstanding on his part of the role of law, the role of judicial vs. legislative branches, and the US Constitution) of simple things like SCOTUS decisions of the day which I had already read within an hour or two of release.
The thing I miss the most about no longer investing time in watching the Daily Show is that I no longer instantly recognize the source of the balderdash I hear from friends and acquaintances the next day. It was fun already having formed a devastating counter argument and dismantling their arguments without a second thought. Sadly, sometimes these people live in such an echo chamber that I actually have to help them support parts of their own positions when Jon accidentally stumbled on a good point or two but didn't have the argument to support the point.
