After nearly three years with my handy iPhone 3 — a product nearly considered “vintage” by Apple’s standards — about a week ago I decided it was time for an upgrade.

I didn’t get anything too fancy, just an updated version of the same phone, but the extra internal capacity allowed to me to download far more applications than I’d had on my old phone.

Most smartphones allow you to categorize these “apps” into various subgroups: I have my notepad, voice recorder and work email in a folder labeled “Daily News,” my iTunes, music and online radio in another. What stuck out to me, though, was the sheer number of programs that fell into the category of social media on my phone.
