There's lots of discussion about Theme Frameworks these days. Apparently, Buddypress will have one soon.
I'm planning to use Buddypress, bbPress and WPMU as the base for a CMS in my niche. It won't be a blog site (think Tastykitchen.com) and will only have one blog with several categories for contributors.
I'm wondering if theme frameworks are as helpful in the CMS environment? Why?
Take a site like Tasty Kitchen (http://thepioneerwoman.com/tasty-kitchen/). Would a themeframework be useful in that situation or would it be better to just build a theme using the default as a starting point?
Another example would be VW Tankwars (http://tdi.vw.com/leaderboard/).
I would like the benefit of automatic compatibility and functionality with upgrades, but question whether it is possible or productive with the amount of customization needed for some CMS implementations.
