Yes, sadly, we have serious technical problems with HTTPS and podcasts.
On the positive side, we are asking for miniminal personal information and your exposure is very limited. All we ask is a first & last name, and an email address. Because we don’t collect any sensitive information such as address, phone & fax numbers, your risk is very low. In fact, we only ask for first & last names as a way to detect spammy webcrawler signups.
We recommend using a personal email address. We don’t need or want personal or professional details about you.
We did switch to HTTPS a while back and about 40% of podcatchers stopped downloading our podcasts so we had to roll back because, you know, podcasting is what we do. We are waiting a year or so for software to be updated and then we will try again. For example, Apple Podcasts now support HTTPS connections, but it didn’t last year.
We have deep technical issues because the website, RSS and CDN are all hosted on different services and each one has a different certificates and issuers for the same domain. We have migrated our RSS provider which should fix the problems that we had there but our CDN and WordPress are still problems.
When we move to implement the payment gateway, that part will be encrypted since the membership system does that by default. We are currently investigating whether to migrate to another platform which will give us greater control but this takes a lot of time that we don’t really have.
Hope this helps. I wish it was different, but podcasts downloads are critical to what we do.
