There's two separate issues to be compared:

"Go read the Sequences" : "Go read a bunch of Feminist Blogs" :: "Go read 'Circular Altruism'" : "Go read a particular article about 'Objectification."

"Objectification" and "Shut Up and Multiply" are buzzwords. They are important concepts that you need to understand in depth, even if you disagree with the ramifications and phrasing of them, if you want to discuss particular issues in a meaningful way.

"The Sequences" and "A bunch of a feminist blogs" are large collections of work that include essays of varying quality and importance. "Go read the sequences" is something I've definitely heard a lot here. Outsiders sometimes assume we mean "I don't feel like talking to you until you're part of our cult" when we say it. When in fact, they contain a lot of useful information that will change your mind about some things - but you are unlikely to start updating if you just read one particular article, especially if you've previously been biased against its topic.
