I started using Mercurial for projects and I am really excited about it. One feature that I think is rather addicting is the RSS feed for commits. This simply rocks! I find that my commit messages keep something of a log of the project. I place TODO items and questions I might have on my decisions and generally give an overview of what I worked on. It really feels like a blog.
I am sure there are some downsides to doing this. I suppose in a huge project if tons of contributors were double dipping by using a mercurial repository as a blog things could get sketchy. At this point though, it really make communication as to what is going on in a project much simpler and easy to manage.
The next step is to hack together an Atom feed instead of using RSS…
