that's a pretty broad area... what specific area of IT are you looking for? I know basic MIS type computer user places, I know some Linux/Unix admin places... a couple Cisco type places. I work with a lot of scary smart people, so I tend to just pick up the phone these days (after a quick google search or 2).
I would say general where they have different topics, just like TB.
For instance questions about software, hardware, networks, security, etc.
I can google some stuff, but it's hard to find feedback from people that have experience with this or that.
