I don't agreed with many of their posts, but if you want to waste your time in the chaotic Chinese political small talks, then maybe that's one place to look at. Also, keep in mind that you reading small talks there, so take everything with a grain of salt.

I personally acquire most of the information on Twitter. I followed many people who working in the IT or related fields, and sometime they retweet political related stuff (As joke or mock mostly). This is how I know about that South Park episode.
