In two recent conversations, one person said LinkedIn is a far better professional tool than Facebook (but he's never used Facebook); another said he doesn't allow anyone in his company to text message (while admitting he doesn't personally like or use text).
And then the next line that always comes up, "I don't have time to manage so many forms of communications."
Aren't those questions the real problem with discussing social media with non-users: Does it save us time, or take even more time? (It's tough to argue the taking time point.) Does it build a community at the expense of other communities? Is there such a thing as "better" if community and networking choices are often personal preferences - whether online or live?
Do choices have to be made with what to adopt? I think yes.
