How Long Is Your... Content?
Say goodbye to TL;DR!
Not every user is going to have the time to go through your long form content. It's a digital fact of life.
Your responsibility as a Web professional is to make the experience as useful as possible, of course, and often, that means being transparent about how much time a user will need to invest.
If you're finding that even though you are publishing longer (and hopefully more engaging) content, but time on site is suffering, consider implementing ReadRemaining.js, a clever jQuery plugin that shows just how long it will take to read through a page.
Consider it a way to reduce the TL;DR references your content may sometimes generate.
