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 :).

In my experience, the overhead in figuring out a codebase is usually large. So taking 5+ new projects each time would mean that you would be spending a lot of time on just reading code.

Now improving code reading/understanding skills is not a bad idea, it is just that it does not seem to be your goal. I would suggest just taking 1 new project each round.

I guess this also matters if you are working on this full-time or not.

Would love to read your experience report as you progress through the rounds.

Part of it is to get experience in understanding diverse code bases quickly, but also to see lots of diverse code bases and styles to see what we like and dis-like about each.

We are not working on this full time, so I expect round one will take two to three months, round two will take about the same. Round 3+ will likely take one to two months.

Great. Let us know how it goes. It has definitely inspired me to atleast run a variant of this.
