I've recently been doing some work with Podcast.co to apply some functional and cosmetic updates to their Craft 3 site.
Together we've managed to create a highly flexible framework for content creation that works well with their rapid publishing cycle. They are absolutely churning out good articles. Linked with some sensible SEO this has ensured that they're in the top 5 Google search results for searches on their key product offerings.
I have a mailing list.
I honestly don't know what I'm going to use it for yet.
Subscribe to it and I might send you some cool stuff.
Not Spam though. That's not cool.
