I actually read the Rails articles quite a bit just because I like to not limit what I do or know to a small subset, even if I do not actively use it. Software does not come to other platforms unless one ports it, after all :)
Disclaimer: not a RoR developer, but I do use Python.
I do understand the lack of support for Opera, with it having just a tiny market share in the US, but it still is a form of exclusion.
I'm glad Opera is switching to Webkit & V8 because besides the many websites breaking I found Opera to be much nicer to use than Chrome or Firefox.
I have all the large browsers installed though for web development, so I can always open something else if needed. I just can't move away from Opera, because of all the native power features I would have to give up or find extensions that may or may not work exactly the same and have future support by their developers. I can say though that unlike some sites I frequented in the past (such as slashdot), I have never had anyone on HN make snarky remarks about me being an Opera user, which is refreshing and quite the opposite of being excluded.
I do think Webkit will help Opera in the long run as well, as long as they do not use it as a reason to throw away their long term commitment they have stuck with to keep backwards support for features and user interface elements. If they ditch most of that on the notion they can just tell users to use Chrome extensions, I would be truly sadden and have little reason to use Opera anymore. I'd probably end up forking Chromium in attempt to make it function like Opera once did and hope other former Opera users would help contribute via code commits along the way. That's just worst case thinking and I'm going to stay optimistic for now :)
Not to get too off track though from the discussion, but the OP (above my original reply) is correct in that there is quite a bit of RoR and Apple upvoted articles (if that was his point), but there are many others in a variety of topics. Perhaps not everyone is as interested as I am about broadening my knowledge of various technologies whether I use them or not, but I think many of us on HN are. Since I don't follow RoR or Apple news that much, I don't mind seeing it, because it at least keeps me exposed to information I don't follow actively on my own.
