I find the show to be brilliant in pretty much every way (although fairly short I s'pose, with each episode ~25 minutes, and only 6 episodes per season).
I guess what I like most about it is that it pokes fun at the typical computer user, as well as fixing common problems, with the whole, "Have you tried turning it off and on again"? As well as problems typically being solved by actually plugging in the machine. Plus Moss. He's probably my favorite character by far (Richmond is second).
Just found out about this series a few weeks ago myself, so I figured I'd check and see if anyone else watches it, as well as spread that it's quite the entertaining piece of comedy.
Anyways, if you haven't seen it yet, it's on netflix, as well as on http://www.channel4.com/programmes/the-it-crowd/4od#series-1.
