- This function is quite different to the others, as it generates an excerpt from HTML (truncating) - Most functions in the meta data folder just contain content negotiation logic, like if post then feature_image else cover_image type things - This function is more like a library and shouldn't live in Ghost, it should probably be in @tryghost/helpers - It's definitely something we'd love to rewrite to work better tooooo
