Reading through Pew Research blog post announcing the highlights of a new report just now (Libraries at the Crossroads), I spotted various Twitter icons around the document, not unlike the sort of speech bubble comment icons used in paragraph level commenting systems.
Nice – built in opportunities for social amplification of particular bullet points:-)
PS thinks: hmm, maybe I could build something similar into auto-generated copy for contexts like this?
PPS via @ned_potter, the suggestion that maybe they’re making use of this WordPress plugin: ClickToTweet. Hmmm… And via @mhawksey, this plugin: Inline Tweet Sharer.
OUseful.Info, the blog... 
I’ve seen CapX (horrible blog, but people keep tweeting it) do the same thing but with pre-written summary tweets – http://www.capx.co/
@David Gets round having to read the story, I guess, if you can share directly from just the headline and the graphic!;-)
I think that’s the idea. Certainly any human being that read the entire article wouldn’t choose to tweet it (other than in the form “Would you look at this shite! [link]”)
A slightly different alternative: I use the plugin Selection Sharer on WordPress, where rather than you (the blog author) deciding which bits of your post are worth your visitors tweeting, visitors make their own choice by selecting text and then sharing buttons pop up (as on Medium, The Guardian website, etc.)
@simon What I have in mind is value add, of a sort, for robot generated texts… so eg crafting certain newsworthy sentences so they’re tweetable, and adding in the sharing link.
