They should also try to make sure all of their descriptions are actually correct. They describe SNS as "AWS Messenger" and say to "Use this to
Send mobile notifications, emails and/or SMS messages". That's only one specific use-case though. Really it should be called "AWS Callbacks", and you can use it to create callbacks from other services and webhooks which can trigger notifications to mobile devices, emails, SMS, or other AWS services.
I don't think you're weird. Instructional or informational videos force their pacing on you. Text and images allow you to learn at your own pace, be it faster or slower than a video.
Few things are more frustrating than having to skip back 15 seconds multiple times in a video because I didn't quite get something, or trying to hunt around ahead in the timeline because the current stuff being presented is trivial introductory fluff.
I am the same. Give me text! I skip around all over the place, and can (occasionally) read (short) paragraphs in a glance. Videos and their enforced pacing :/
