I'm interested in setting up PPAs for a few projects that I'm working on, and I'm trying to find out how many PPAs I need. Should I create one PPA for each project, effectively having a single package in each? The fact that the name is "personal package archive" and the fact that they're created under my launchpad username make it seem like I should have all of my projects in one PPA - would that cause problems? What if it's multiple similar/related packages, such as unity lenses?
The instructions don't really say anything about how much to put in a single PPA, though they do indicate having more than one is okay.
