I am thinking of building a new website in Joomla 3, a magazine/blog-type thing. I understand that K2 is great for J1.5 and 2.5 but I wondered if there were still major things that K2 did compared to Joomla3?
Thanks

Easier templating and development,

More flexible templates,

Multiple subtemplates and template inheritance,

Comments, related items and the latest items from the author,

Author (blog) pages,

The K2 content module which can be overriden to become almost anything you imagine (carousel, tabs, slideshow etc).

SigPro and AllVideos integration (the ability to control where in your template the video appears).

Thanks a lot for the answer, that helps.
