what exactly do you mean by more technical? technical as in finance-technical (mathematic, algorithmic trading, etc.)? or technical as in more related to the breed of content on YC?
I guess I meant the former, but both work. I've been building up a large collection of blogs with this sort of info for my own reading. (I've put some up on http://quantblog.com/library , but the whole site is still a work in progress). I can email you a larger list or post here if anyone is interested. Again, this caters to my interests, you may have other ideas in mind.
