I have very good contacts with my ISP (habari node), and the tech crowd here is mostly centered around the Arusha Linux User group, so it might not be super relevant for you if you're in Dar.
I suspect Dar would have more tech stuff going on - the ubuntu-tz LoCo seems to be mostly based in Dar for example.
