Exactly, so if the blog doesn't have RSS, you know they're probably made from marketers with no input from engineering, otherwise they'd have RSS on the blogs.
Edit: Ah, noticed I made a without/with typo, fixed that, should make about 2% more sense now for the ones who the original meaning was unclear :)
> It is to signal that these (those with RSS) aren't really "engineering" blogs at all
So now when I corrected that with/without typo, it looks like your previous comment doesn't make sense, but it kind of did, at the time. Sorry about that and thanks for making me realize the typo!
