In last week I was working to add a new developer metrics to MondayMetrics and it is ready now. Now you can track your "Hacker News Karma" with MondayMetrics.
We already have the following metrics tracking:
-- Github Followers
-- Github Repo Star
-- Twitter Followers
-- Instagram Followers
-- Hacker News Karma (new)
So if you want to track yours, start here https://mondaymetrics.com
