To our readers and blog authors — your support of SDA has been outstanding through the years, and 2025 is no exception. I spent last evening sending notes to all who contributed, but a handful of those bounced back — so I’m here this morning to thank you all again, and let those whom I may have missed know that we truly appreciate the support.
While I could monetize the site with ads and pop-ups, I prefer the voluntary funding model because it preserves our editorial independence and keeps your reading experience free of that particular annoyance.
As we push well past our 20th year, you can trust that SDA endures because we have something to say – not because we’re working a grift or pushing narratives on behalf of an undisclosed funding source. It’s gratifying to know so many of you appreciate what we do here. Thank you all, as always!

The business model of SDA has always been “this blog runs on the volunteer effort of people who enjoy yelling at radios, but your donations are appreciated”.
