Show HN: Plus – Self-updating screenshots
I worked for a personalization vendor a few years ago and was on an engineering team that built a feature like this.  It was ... a major headache, and I don't think anyone was ever completely comfortable with the security implications.<p>So I wish the team good luck, and especially with issues like:<p>* A/B testing.  How can you ensure that what your clients are seeing is the same thing you are seeing?  Maybe you've been assigned to different A/B groups.<p>* Extensions.  What if your clients are using Chrome extensions that affect how the page is rendered?  How can you replicate that?<p>* Networking/auth issues.  What do you render if you're unable to connect or log in?
