Help me choose a good theme for a blog

Hello all,

I'm putting a blog together for someone and they've requested that the blog homepage is essentially a condensation of their online life. The idea I think is that it allows a one glance update of all their thinking. Not a bad idea as it goes.

I've found a really nice theme called Persona from Colorlabs (who I've used before a long time ago and know to be trustworthy), you can see it here:

I'd rather keep to the WPMU Dev path though - and avoid spending $65 on another theme. Does anyone know of any good alternatives which allow you to add blog posts, add Twitter and Instagram stuff onto a single homepage?

Any suggestions?
