I scraped a bunch of meta-data about Dribbble uploads. Maybe you're intrigued by that? Maybe you want to go hunting for the first occurrence of 'flat design' or the last of 'skeuomorphism'? Please do.
I've pulled down every upload as-far-as-I-can-tell from the site's very first through the end of August 2013. If it feels incomplete to you, let me know. Or complete it yourself, and merge the data in.
The meta-data I've scraped includes: dribbble_shot_id, created_on, title, tags, likes_count, views_count, comments_count.
The URL for any Dribbble upload can be created by appending the dribbble_shot_id to http://dribbble.com/shots/ (i.e. http://dribbble.com/shots/[dribbble_shot_id]).
I've made a brief and incomplete attempt to analyse this data, but I'm no statistician or big-data-cruncher, so I'd appreciate it if others had a go.
