We've been using K2 for about a year and a half and it's the best thing that ever happened.
It allows my writers to go in, post, add images to the gallery and a main image rather easily. There are a few quirks but might be more my doing (I'm not the best web developer, lol, but I do what I can) but at it was very easy to get acclimated to.
I can't wait until it's stable for Joomla 1.7 so we can update. I've gotten a peek at the 1.7 version while making a site for a family member and it's just gorgeous! But we won't upgrade until K2 is ready, otherwise we'll stay in the dark ages of Joomla..but still looking fabulous.
