I don't think it works like that.
However, I find the 300 posts almost unbelievable. You know, I've been following his posts for more than a year now (yes, ALL his posts) and it certainly doesn't feel like he made 1 post a day already. Yes, there was more activity around march/april or whenever the first ST3 betas were released, but was it really that much?
Anyway, I don't think I need to repeat what others already said.
@quarnster: I agree 100% with what you say, except that ST probably has a lot of underlying code that you did not implement yet. However, I am really excited for your editor project. I don't know any Go but I am following. (Also, when you're implementing an API, I beg you to not only support the sublime API but also provide your own less clustered API. )
Maybe the other 2 employees are more verbose that Jon, but since they don't seem to have joined the forum we can't really see anything.
