I saw your message in the wiki-research list. Very interesting stuff! I recently I had an idea of something to look at something on wikipedia that would entail exactly looking at article structures and how they evolves over time. Not a big project, but just an interesting thing to look at. I am very curious to hear more about your plans, both ideas and practice. For this thought I would have thought to compile a diachronic corpus of comparable wikipedia articles, but your visualization tool and pipeline is something I would like to try. I've got some basic python scripts to get the data, but when getting around to it, there's probably better off the shelf tools or histories of wikipedia compiled. I'm not really a techie, so all the scraps of code I've done have been for very particular purposes. Unfortunately with the current workload, I am sure that I am not able to follow this up any time before summer.

I see from your grant that we even have some similar background, as I have dealt with cultural evolution and language evolution before. I hope you get the grant for this, and will be interested to hear in how you progress. But only answering in a hurry, and might not pick up the trail soon. 

Best of luck! (Endorsed your application too ;) )
