If you're talking about coding projects, then I like one at a time. Sometimes I split that to be one at work, one at home. I find that when I flight a lot of other ideas when I already have a major project in the works, I end up with a lot of sparse git and svn repositories. That's just my preference. I can handle a handful (5 or 6 maybe and still be effective?) but the context switching saps my productivity pretty fast.
