Well that's... certainly a take. But I have to disagree. Most traffic coming to blog posts is not from people who know you and are personally following your posts, they're from people who clicked a link to the article someone shared or found it while googling something.
It's not hard to add one line of context so readers aren't lost. Here, take this for example, combining a couple parts of the GitHub readme:
> For those who are unfamiliar, the Sanitizer API is a proposed new browser API being incubated in the Sanitizer API WICG, with the goal of bringing this to the WHATWG.
Easy. Can fit that in right after "this blog post will explain why", and now everyone is on the same page.
