Donating to Open Source

I have decided to start donating a small amount of my fun money to open source projects. After some research, the initial set of recipients are

• Magit
• Perl 5 Core Maintenance Fund
• XMonad

These are important to me, they need more money, and I believe they can use donations well. If you disagree, I’d genuinely like to hear what mistakes I’ve made in the analysis below. I hope it shows that this is important to me.
