Why not make the attendant have the People You May Know block displayed? It's kind of useless in my opinion, like if you just opened the network, it will not display anything. This might be good if you already have a big community.

And why don't we have a similar bloc, like suggesting friends of friends with groups, spaces?! Groups, spaces you may like. And please make the blocks of popular, active, featured, etc, items have a smaller view, they are too big for a small sidebar.
