This is excellent! I dreamed of such thing all the time.

Do you mind sharing some technical details on how did you implement data collection, diff, search, aggregation, etc?

then, clone all these git awesome repos, parsed their readme by mdast, split with list-item, or heading, got these items updated time by `git blame` command, added these items to database.

Then, I used gatsby to build a static site, 2 times deploy per day.
