Right, your objection is that we're excluding people, and you ask: > Is that what we want to do here? Yes. Just the fact that articles are oriented on tech excludes a whole host of people. And if you include too many people, that in itself will start to exclude people; in addition, the discussion will fall apart. You're looking at it as a moral issue, and you're not wrong to, it's just that the morality is very much overshadowed by the practical mechanics of running a discussion forum. I recommend "Choosing in Groups" by Michael Munger for some very insightful thoughts on how this all works.
