Hi @playfulfoodie - Have you ever heard of an "elevator pitch?" It's the short sales pitch that convinces the buyer to hear more about it or buy in right away. Don't be fooled - you might not think you're selling a product but in blogging you are selling yourself to get the most views and feedback. On Steemit, that equals earnings.
Think of your first 100 characters like a Twitter message. Put in a lot of information in a small amount of space. It should compliment your title without being a repeat of the title. That is the final hook which draws us in.
That's a great way of looking at it, thanks! I'll definitely try to aim for this in the future.
