Truthfully, it probably doesn't. A good haiku is more than just a syllable count, it has a spirit of simplicity and beauty, and usually a 'turn' in the last line.

Personally, even though they are not 'good' per se, I think haikubot reminds us that there can be beauty in the ordinary.

Talking to you, for example, is haikubot's fault. This silly bot created an opportunity for us to connect. Maybe it is trite, sure, but as my grandpa always said, 'better than a sharp stick in the eye'.

Blessings to you!
