This ended up getting tossed back and forth, debated, and more. What it finally boiled down to is we're going to be working on 8.0 next which will update the UI among other things and blogs will be added at the same time.
Speaking of blogs, I'm actually trying to actively use mine so I can get an idea of what I like about them, what features we need to bring over, etc. A common mistake I've made in the past is when we add a new big feature, I've never really personally used it (such as photo gallery software) so I didn't really get a good idea on what features we really needed to have.
So they are coming for sure, has taken much longer than I would have liked, but they will be in 8.0 as a definite feature.
