This Wordpress theme by Solostream offers critical magazine-style features with some emphasis on community. A big check to my #1 must-have — a category-based nav — as well as a large and potentially auto-scrolling main feature. But prominent too is the “most popular”/comments/tags/etc block on the HP; recent comments and gravatars get play as well. Comments on the article pages are nicely color-blocked.

The version I’m referring to is the version in the live demo; the theme comes with several different layouts for its HP and category pages.
