Hello. I have a quick question. How does digg.com work? Is there any open source lookalike? Many thanks!
I'm sure their just passing some sort of ID to the article which just increments it's "Digg" count. Not sure about an free lookalike but it can be programmed with ease. Notice i didn't say fastly, but, with ease, because I'm sure their infastructure, site, db, etc... took a LONG time to develop, and im sure it's continually being improved. Maybe a solution would be to use their new API to build a structure with your own "SKIN" but using their backend? http://apidoc.digg.com/
Digg runs on LAMP using prototype as the Javascript/Ajax backend and is really simple to make just VERY time consuming. Diggs mainy impressive because of its scalability.
