Paul Hammond on why you might want to use if statements at runtime to control what features are enabled/disabled. Your version control system's branches are designed for enabling/disabling/merging features at compile time. Not runtime.

Pre-built version control tagging/macro supports for LaTeX. Yes!

Roughly speaking, like Mercurial or Monotone. Not sure how it compares to git w.r.t branching, speed, index. Big selling points would be integrated bug tracking and wiki and a single binary, with builds for Windows, OS X and Linux. Uses SQLite for the repo. No worse than hg/git rolling their own, probably better than svn using BerkeleyDB.

Really nice article on how to write commit messages. "Reveal your intentions, don’t describe what the code does. Tell why it does it."

How you should format commit messages when using git, but just as good for an version control system.
