Pretty sure I was using TB to read RSS back in 2006 or something like that...

Both of these comments are needlessly snarky. Although it is true that the RSS capability of Thunderbird has been around for quite a while, I enjoy articles that simply reflect the author's discovery or use case.

Like you, I was consuming RSS through Thunderbird around that time as well and thought it was really good. I have since moved to something else(many times) as my needs have changed.

In the spirit of HN, the poster maybe wanted a discussion of how the use of RSS has declined and walled gardens took its place which is not good for the longevity and usefulness of knowledge.
