Don't bother with HTML layouts. Stick with the standard formatting, and use bullets and other visual breaks to keep your post as easy to read/skim as possible.
Try using an image editing app like
Canva
to add text to your images. (Keep the look clean and the text to a minimum.) This will help your images stand out, and will help to get your message across faster and more effectively.
And keep posting! Even though Craig is making more work for marketers, that doesn't necessarily mean it's time to stop posting there. And while you're competition drops off, it will give you a better chance to be seen by potential prospects.
