Just as a curiosity, the feeds shown through FBs various channels are different. I've switched to the mobile site after using the dedicated app and noticed much less random things-tangentially-interesting in my feed but with more of a focus on my immediate friends. It's surprisingly made FB a much more enjoyable medium for me as I can keep tabs on the personal lives of a few close members in a fairly chronological view. Anyone know possibly why there is these differences or can explain exactly what's going on here?
