I've decided that I want to use Mercurial for a small, personal project.
Most of the help I've read about it talks about merging changes between multiple users. Since I'm solo, that's not going to happen.
Should I have multiple repositories? My development computer is already backed up nightly to my Windows Home Server, so it doesn't seem valuable to have a second repository elsewhere just for backup purposes.
Should I be branching every day? Or just around releases? Or when?
In general, what practices do you recommend for the lone developer using Mercurial?
