May I suggest my friend Tim's blog? I'm pretty sure it's unknown, it seems he writes it mostly for himself. But there are some great technical articles on it:
Reading the top blog entry, looks like a very useful blog to me. No big fancy talking about how he scaled up to 4 million users, but a down-to-earth story about FTP and versioning that I can relate to. Thanks for the link :)
Edit: I forgot to mention another thing: It made a positive impression by being a dark blog with a good design. I don't entirely like my own blog's design, and I thought white-on-black just wasn't a good setup. This shows it can be great. I also like the lack of "recommended articles" and pop-ups (javascript ones) to keep me on the site.
