I believe their desired audience is that 99% (now that the core tech crowd has left). Have you seen the programming section's 'popular' page? It's practically barren. That's how you know the original tech crowd left. In Digg's prime that section was poppin', so to speak.
That's kind of what the parent comment was pointing out. There aren't really tech geeks on Digg anymore, and the presumption is that only tech geeks care about not having the DiggBar. So maybe it doesn't make sense to get rid of it, if most of the people on Digg don't care anyway.
