Mention is a useful OSN feature that hasn't been mentioned enough. It is a replacement for awkwardly copying and pasting the hyperlink when you find something interesting on the Internet. So instead of putting a long link in an email or spamming your own social media feed, simply @ them where it is.
We recently added a new highlight function to it so now you can also highlight a paragraph on any website for your friends to see. Sounds nice? It is super easy to use too.
