I posted a question in MSO about adding style to the Can you help? text. This text will appear for those posts that don't have any answer yet, like:

Can you help? Stack Overflow depends on everyone sharing their knowledge. If you're able to answer this question, please do!

But in the comments, some users are still seeing the old help text, like:

Know someone who can answer? Share a link to this question via email, Google+, Twitter, or Facebook.

Based on what logic is the different notice appearing? or is the notice appearing randomly to users for an A/B testing?

Note: The notice is not specific to SO; it is showing for most of the Stack Exchange sites, so I'm posting the question here.

Screenshots are from the comments section of the MSO question:

New notice

The message there is currently being A/B tested, which is why different people (well, things like user agent are involved, so same person on a different browser, for instance) are seeing different things.

  • How are you determining "success" in an A/B test like this? Based on whether or not the question gets an answer? – Cody Gray Jan 12 '17 at 10:34

    @CodyGray - a few different metrics. One is which one is getting more answers, another which one gets better answer quality. – Oded Jan 12 '17 at 10:39
  • what is the definitions of better answer quality, beside higher number of votes? – Ooker Mar 3 '17 at 19:17
