I don’t think I’ve seen this before. Imagine a (well designed) “profile” website like About.me where you can select your top 3 used social media streams (e.g., Twitter, Instagram, Quora) and it shows 3 columns of only your most recent activity.
Why do I, as a stranger, want to comb through all 80 of the social sites you list in your email footer or on About.me? Instead, as someone who’s viewing your profile page online, I’d rather just get a sense for it by viewing your latest activity in a glance.
You can still have an awesome-looking, full-page picture background, if you want, though that might conflict with the your Instagram stream…
