Lets not get so caught up in the numbers! (I am saying this as much to myself as to you)
There really isn't much that can be done to change the numbers significantly in the near term, growth is basically a function of how many of us invest genuine energy into helping people we think might actually try linux get over the initial reluctancy and learning curve, and if done right that is going to be a slow process of interpersonal connections and self help guides people seek out after deciding to really give it a go.
What matters is how possible it is when the next major upheaval in operating systems and consumer's tolerance of their bullshit really happens in force and that it is finally enough for a good chunk of users to cave off and say "fuck it, I really am going to linux this time". We can't precipitate that tipping point, we shouldn't try to necessarily in my opinion (other than pushing for structural adoption of linux like say on school computers) because it will just feel forced, but what we can do is make the tools work well, we can experiment and tweak and keep making this place better and better so that when that opportunity comes no matter how close or far it is, the tipping point will engage like the transmission on an extremely expensive luxury car, it will just be a smooooottth departure and it will leave corporate tech companies reeling how fast they loose their incredibly unbalanced power over our digital lives.
