Yes, this is true. I will be involved with the Twilio blog as part of my duties, by writing original articles and also by working with other contributors to get their posts published.
oh nice! Long time fan of your work and I people get us confused sometimes because PacktPub chose the title 'Flask by Example' for a book I wrote with them which is too similar to your blog posts.
I nearly wrote an article for Twilio but didn't complete the process. But have written similar posts e.g. [0] and work with other writers who also do this form of instructional technical writing. Would love to chat sometime if you have time - contact info in my profile
