@Bruce No you got it with the first reply, although this second one is also apt. I'm not sure if it's normal to talk about your values with other people... of course a lot of discussions are probably about that even if it is disguised as something else (issues, etc).
As far as tech goes, I think there are a not insignificant number of people for whom the usable alternatives to the mainstream are entirely unknown; the fact is big mainstream tech spends a lot on marketing, whilst even the best alternatives are invariably run with so much as a budget for a paper posters. In this instance I saw we are the advertising, even if not directly, for example taking part in some of the things you mentioned -- how about we see some of that in blog posts and we share them!
Micro.blog itself became more than intended insofar as pace of growth thanks almost entirely to word of mouth, and whilst not every single thing made by those of us on this side of the fence will get Fireball'd or whatever I don't think it is necessary; merely building posts and posts covering the nuances of these issues across a multitude of blogs... now there is your impact. Too many times I search for something and there are scraps to be found, barely any blog posts let alone useful things. I think this can change and it's only if we're allowing to independently stand up and say the things we believe, whilst sharing the things other people say. Sure, at some point people will create collections of these things for reference thus making it easier to access from the mainstream POV but that's not the most important thing; rather, we must focus on the creation of this... this weird thing we used to call being on the web. Let's get back to that.
