git diff/merge on xml files would be really great. will think this over.

I'm thinking of building a productivity tool in the legal space. The big inspiration I had a week ago is that I could use git or another version control system for features like git-diff and git-blame.

I'm now thinking about how most elegantly add markup features for things like highlighting text, adding labels, inline commenting, muti-media embeds, and text formatting both simple and complex. any suggestions? The naive thing to do is to include a <span> based markup format that complements what is already being done with font-size,color etc but im worried that it will become a mess. Both in terms of document size and git diff.

also, are there any examples of products that successfully leveraged version control systems to create large project management tools?

Oh munn, always chiming in at unfortunate times!

Awesome. I'm at a startup now that could totally leverage this tech. Thanks!

Named captures in regular expressions looks really nice! I'm especially excited to play with Oniguruma.

I like this. I wonder if there is a way to have a left nav like this and then a right column for comments.

I'm in agreement. Jordan Cooper's posts are thoughtful and coherent.

Fred Wilson pen's many of his posts on his blackberry and in many ways that adds to the conversational tone he tries to set on his blog.
