While I admit to having skimmed over the paper above, this is NOT the main source of our information.
We looked a bit further into this one:
As soon as I get home I will give credit where due, my bad.
I couldn’t help but notice the ‘.cfm’ extension in the acm.org link submitted by @mockery  so I thought i’d google a bit to see what tech infrastructure acm.org was running because i found it interesting they’d be using coldfusion. The search led me to a project on github  who’s file appeared in the results  and made me aware of ‘citeulike.org’. I did a quick search with algolia to check if citeulike.org hadn’t been submitted on hn already. This made me aware of user @sharpshoot and led me to research him a bit and bookmark his site so I can read about how he ‘made it’ (i’m an aspiring entrepreneur you see…).
Anyway all this made me wonder if there is a software that automatically does what I had to do manually, how efficient it would have to be and all the ethical issues surrounding it’s existence. Thin line between useful and scary…
I believe the source was released somewhere, but I don't seem to be able to find it right now.
I love the stuff Introversion does.
