Stumbled on a link to this in another article. I was literally planning to use this feature to set up a list sometime this week that I could use to narrow down the FB firehose when I only have a few minutes, in hopes that I might actually keep up with at least some of my friends instead of avoiding Facebook because I’m so far behind.
So much for that idea.
