¿†Love†?

Topics to be probed after finals:

Why are there so few options for punctuation marks at the end of sentences? Would language be more efficient or expressive if we had access to more than a "." , "?" or "!" ? That is, with punctuation marks that can add a variety of different additional overtones to the sentence, we wouldn't need to express certain meanings using additional words, but could just use the punctuation mark at the end of the sentence to denote implied meaning or emphasis. Or, conversely, for example, we could really experiment with more sophisticated types of irony with a bigger palette of punctuation marks to choose from.

Why are the majority of songs we hear about love? I've wondered about this for years. I suppose a lot of people are inspired by love, but people are also inspired by an inconceivable number of other things as well. (Like this little known gem, which I suppose can still be considered a type of love) Is the fact that love (or lost love, or hatred because of something that happened because of love, or love for God, or hoped-for love... you get the idea) is simply the greatest common denominator, and thus strikes resonances with more people? I find this doubtful. Remember, back in the day, when bard songs about warriors and mythical beasts were all the rage?
