I’ve just come across TechEssence
It seems to be the right place for librarians to go for a straightforward understandable discussion of a whole range of technologies from Ajax through RSS, and FRBR (whatever that is), all the way to Unicode. And there are good posts as well on tech-related matters.
They hype the site with this para, though:
You’re busy. You don’t have time for a lot of jargon, techie posturing, or attitudes. You’ve come to the right place. We don’t put you down, we don’t talk down to you, we just give it to you straight. Come here for accurate, understandable explanations of important information technologies for libraries. Go elsewhere for the hype.
…which seems to me like a tad of posturing and attitude itself.
