Add one more to the list of things that you can “Like” on Facebook. Starting today, you can Like comments that others have made. You can also UNlike a comment if you change your mind later.
As ReadWriteWeb points out, this could mean some pretty cool features in the future from developers. “Imagine the addition of “people whose comments you liked” as a metric by which to measure future content for prioritization or other analysis.” This could prove to be invaluable for those of us whose jobs and lives depend on community engagement.
If you really enjoy a comment someone had made anywhere on the Facebook site, you can simply Like it instead of spending time to write out a comment of your own. There are a LOT of times where I see someone post simply to say “I agree with you!” or “I like what you said!” Now you can just click the Like button and be done with it.
