I've read about Friendcaster, Fast for Facebook and some others but haven't tried any. FB Messenger may be a fine app, I don't know, but I'm not too keen on FB telling me I must install a second app when I only send messages on FB when I am already using FB. Otherwise, the stock Android messaging app meets all my needs (I even tried Google Hangouts but didn't like it as much as the stock app). Any input is appreciated! - kwhopson
