I want to tag my friends so I can can quickly check feeds for "colleagues", "competitors", "stalk-this-hottie", "family", "important", "not-important" and so on. With 700+ on Twitter and 400+ on Facebook it's unmanageable in a non-discerning aggregator
How are you going to deal with double posts? Like for example if someone updates their Facebook profile with Twitter and I am following both. Maybe you can remove this redundancy
