This looks interesting, but it would need proper, nested subforums that are more discrete than the current tag system to really substitute for any of the major forums I use. This isn't because of navigation, but because of the alerts and other cruft that particular sections in large, long-used forums accumulate over time. Per-section alerts (boxes at the top of the page separate from threads) in particular don't seem to be replicable here outside of the descriptions at the top.
