I’ve not been a fan of QQ the IM client, ever since its malware phase c. 2002. I used it to practice typing Chinese with friends online, but it forced me to use “Tencent Explorer” as my default browser as long as the software was installed. I have never forgiven Tencent for that.
It’s my experience that while this app doesn’t do anything that other apps don’t do, it’s especially fast (even if you’re outside China, I hear) and easy to use. Also, its limited selection is a blessing in disguise. It offers a lot of the popular TV shows and movies (including my favorite, 非诚勿扰), and saves you the trouble of having to search on Baidu video or bittorrent sites.
Remember: this is a free app with no login required. I suspect this is all a promotional trick and that we’ll all have to log in with a QQ ID just to use the program eventually, but that doesn’t mean we can’t enjoy it while it lasts!
