Every time Facebook changes its look, I’m reminded of how the things people post online are not really an adequate (or at least not complete) reflection of who they are or what they care about.
There are always tons of posts about whatever FB change has just occurred, even from people who rarely post. I don’t want to call it whining, but a decent percentage of them are usually stating that the change has negatively impacted them in some significant way. If measured by these attributes (posting frequency / percentage and degree of emotion or conviction) their “relative” degree of interest in the FB UI would seem to be high.
Thankfully (hopefully), we can be sure that for most people it can’t really be that important to them relative to all the other stuff in their lives; it’s just that they just choose not to post much about those other things for various reasons.
Food for thought…
