Considering that it's the "other" DVCS often considered along with Git and Mercurial, I thought I'd give Bazaar a try.
It's not working out so well so far. I guess I'm too used to Hg; I found its workflow agreeable.
Thanks to Dave Dribin, and his analysis of git vs. Mercurial, I decided to give Mercurial a try.
It turns out I rather like it! I'd been keeping a lot of my work in Subversion, which is a pretty good centralized source code management system, but the usual way of using it seemed so heavy: branches and tags and all kinds of operations took big URLs.
