A point of feedback - I write a lot of code that gets used by lots of people, and I don't do any of it in a social fashion because I'm entirely uninterested in creating a brand for myself as a developer. All of these metrics you're talking about would screen me out, whereas a simple "created and scaled FOO with BAR set of technologies, used by 100,000/1,000,000/10,000,000 people/month" on a resume would probably get a good amount of employer attention, for good reason - that's an indication of a real full stack engineer who has faced a gamut of real problems. It's not as easy to quantify, but you should probably take that kind of thing into account, because it's a lot more meaningful than the number of people signed up to receive my quips about how much IE6 sucks or how many side projects I've open sourced.
