This list replaces a centralized list. Maybe with the magic of git this will work better. Or maybe we need better community building and connection around such list.
But since such a knowledge source is highly useful for people, and very valuable and people could get lots of credit for helping(in theory), i could see something like this built up.
On the other hand comparing just the current list(5 days of operation) , with the best openhub or github search could offer for the queries "python cryptography" and "python xml", i don't think analytics alone should do. But sure analytics can(and are through Google/Github) being used to guide curators.
