According to feedback on ProductHunt, the most significant problem we have with GitHub User Rank extension is that the data source (namely, GitLance) ceases to provide relevant data to the community. I e-mailed Geoff from GitLance personally on the matter via e-mail, but I haven't heard anything from him yet, maybe I got to spam, who knows?
So, the best freely available source of rankings I could find currently is GitAwards. Despite relatively simple calculation mechanism, it offers us up-to-date stats, so I'm seriously considering it as a substitute for GitLance in the short term.
What do you think? Please vote if this idea bears a value to you.
If you have on your mind alternatives that we could use as a data source, let me know here in the thread.
Thanks in advance!
P. S. Honestly speaking, I would prefer something more sophisticated to be our key algorithm in the long run, but this isn't something we can do quickly. I haven't dug in-depth, but nodal analysis seems promising to me, though 1E8x1E8 sparse matrix calculations might be challenging to implement and run adequately. So to say, it's not a project for a weekend if we are talking about writing own GitLance API from scratch. :)
