TL;DR – Smart Reading Timer Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
TL;DR is a common short for “Too long – Didn’t read”. This plugin allows you to put a small snippet next to each post which tells the users how long it would take to read the post, just like in Medium.com.
This plugin is smarter than most reading timers, because it takes into account the images and the videos of the post. In the future there will be even more support for image height, better support for media (videos and mp3s), and more!
This plugin can work on any theme but it works best on themes that support TL;DR.
