The reason we picked lots of projects is to narrow it down to 5 we might be willing to actually spend our free time working on, thus actually fixing lots of bugs in our favorite 5. I expect the top 5 will not fluctuate much over the rounds, as our first 20 are seeded with projects we already know / work on.

Good point about languages. Since my brother and I have used very few languages we focused on the desire to expand on that. But for those that have used every language under the sun feel free to pick a languages you have not used in a while :).
