tl;dr
Have you ever found a really interesting article that you wanted to share with your friends? Are your friends too busy (or too lazy) to read the articles that you’ve sent them?
tl;dr is just the tool for such situations.
Paste in the URL of the article and get a quick summarised version on a simple, uncluttered webpage. Send the summary to your friends instead and it’ll come with an attractive link preview to better entice your friends to read it.
