Out of curiosity, have you found anywhere on the internet that is both tech-focused and does not have a liberal bias? I'm sure you could find places that lean libertarian, but I don't know of anywhere that I would consider traditionally conservative
To add to your point, I feel that the conservative views on this website are also generally intelligent and thoughtful, even though I mostly disagree with them.
In years past, I frequently found that techie oriented sites tended to lean libertarian (or "classical liberal") more than "liberal" (in the modern sense). In the early days of HN there was a much more markedly libertarian bias here (IMO). Hardly surprising though, given that at one time there was such a close association between tech and libertarian thought that people coined the term Technolibertarianism[1].
But it seems to me that the zeitgeist here has drifted more towards the "liberal" camp over the past few years.
Yes, the uncommondescent blog is heavily conservative, and science and tech focused. But, in general there is a correlation between tech and liberal or libertarian. But this is because that crowd tends to eschew the time consuming obligations that accompany a lived out traditional conservative viewpoint, which would prohibit one from heavy online participation.
There are the Breitbart and Fox News message boards, but that's mostly an older crowd with much time on their hands. The 20-30 conservative crowd is probably busy raising families and being involved with their communities.
