Showing that yes, /A/ does match 'QQQQ'A/B Testing is a bit of a catch-all phrase for "testing the effectiveness of website changes." Strictly Speaking, A/B only refers to the testing specifically is testing of one change "A" against another "B". You can have multi-variate testing as well where you add in a third group "A,B, or C", or mixtures "ABC vs AB vs AC vs BC vs CONTROL"... it's up to the test design.
But basically it's a tool to help you see if the changes you make to your website will work, while the website is up running, using real users. So, for example:
* If your goal is to get more downloads, maybe you'll tset some page layouts or images and see which test group clicks the download button more
* Or, See which splash page results in the most "Sign up for Newsletter" clicks
This is great information for marketers, or really testing out any old thing you want that is trackable through browser-events.
Really though, this is just the tip of the Iceberg of what is possible... but I'll leave it at that. If you really want to know more let me know.
And plenty of people are still using IE8 and Windows XP, and will for the next few years, so I don't think it's really more critical to learn HTML5 than over HTML4. Actually, it's hardly even possible to learn one without the other.
