Slack&#x27;s Reactji -- which lets you use any standard or custom emoji as a reaction -- is significantly more useful than Facebook&#x27;s very limited set of options, <i>and</i> it came first.<p>You would think that after seeing how well received the Slack Reactji are, Facebook would have expanded its available options.<p>I can understand not venturing into custom emoji, but at least let there be a :pile-of-poo: reaction!  After all, it&#x27;s an election year!
