Re: What should be a Plugin, and what should be in Core
johnhiler, if you like plugin-centric development, you should love the bbPress plugin so far (hopefully) 
Hopefully it’s able to walk the line and offer the best to both.
What is a plugin and what is core is always one of those topics that tends to change and drift with the times. 6 years ago having properly formatted links to someones blogroll was considered important enough for WordPress core, but chances are people are using that functionality less and less as time goes on and people are able to connect to people more quickly and organically.
kevinjohn, we haven’t tackled it in the plugin version yet, but the difference between a ‘category’ and a ‘forum’ will be fairly distinct once we get it going. My experience working with the Categories Hierarchy project back in my phpBB days taught me the importance of handling the way those types of data behave.
