To date, it seems that both Snapchat and Facebook happened to be high-profile users of Google’s beta testing system, where they used it to gain user feedback in order to further refine and enhance their mobile apps. Right now, it is not possible to run the existing, stable version of the Twitter app in addition to the beta version, so it is a decision that you will have to make for yourself. If you want to be a beta tester, be prepared to go through a variety of known and of course, unknown bugs and glitches. Hey, there is a price to pay for everything, and at least you get to brag to your mates if all goes well.
