'Average user' just means all traits proportionally blended together, right? Lemmy users are not a huge part of the internet, but our contribution to the 'average' is just a big as any other person; and our opinions and knowledge and behaviour does matter. Some might argue that the opinions of tech-focused people matter more because they are more likely to influence other people about tech decisions.

So yeah, we're a niche group - but the discussion and sharing of ideas is important.
