In other words, the tagline of Facebook’s blog post is indicative
of everything that’s wrong with this feature: “Joel Seligstein, a
Facebook engineer, is relieved he no longer needs to keep track of
which friends like texts vs. email vs. chat.”
He designed this feature to abstract away texts vs. email vs.
chat. But 99% of real humans don’t care about this, and won’t
experience his “relief” because this was never a problem in the
first place. Teens always text each other, because they always
have their cell phones and this is the way to reach them. And to
reach your grandma, you use email. Simple. No mixing up grandma
with your girlfriend.
