Ask HN: How many side projects do you have going at one time?

When setting up my first site, it wasn't called a "side project". It was my full-on hobby that I spent all my weekends on. It was split up into three separate niche sites in 2002.

Since then, I've launched some side blogs, and then two more real sites. The latest has taken up a large portion of spare-hours home time for the past 6 months.

Meanwhile, the original project is still the most popular, but doesn't get a share of my brain power since the newest project is on the go. Having my wife help with customer support these days helps a lot, but there's still the question of further developing the sites.

HN, how have you dealt with this type of multi-side project approach, juggling with the rest of life?
