People who describe themselves as "young-ish" similarly evoke images of crummy half-baked ideas. Things grow. As you grow older you will learn to try to not discount the entity you are presented with now based on impressions made in the past.
Well, the blog is full of crummy half-baked ideas, not to mention weird rants written in panic while on drugs. My professional work is not described as something by a young-ish person.
The thing is, it's too late to change the average (intelligent, well-informed, willing to try new things) user's perception of Linux. For a while, people like classical musicians were trying Linux because it seemed like the better alternative. They gave up. The world gave up.
I never once mentioned in the blog post I use a Mac. It's just something in the background. I don't think about it. I use Windows at work, incidentally. The taskbar works differently, but I'm not playing OS freak anymore.
Oh. On growing older, I'm 25, soon to be 26, and actually trying to present me as younger. I wish I was younger, I wasted my teenage years and I'm trying to live it now while growing to be "serious" professionally in parallel.
It's an interesting thing. I have had two relationships with 30-year-olds who are in the same late-adolescence trip I am. Anyway, that's a personal rant.
