You don't need any introduction of OMGUbuntu. They are by far the most popular Ubuntu blog out there. They had a complete site overhaul recently and I have to say, OMGUbuntu website looks absolutely gorgeous now.
I would say OMGUbuntu is not only a hugely popular blog now, but also the most good looking blog in the whole Linux world. I believe OMGUbuntu could be a lot of help for newcomers to Ubuntu with its non intimidating 'newbie-ish' look and feel and quality content(of course). Best wishes to everyone at OMGUbuntu from Tech Drive-in.
