Moderately useful. Reads mostly like a stereotypical education blog where all the posts link back to Teachers Pay Teachers, and that's actually kind of annoying. The resources that the QR codes lead to are mostly... not helpful? They're impractical and infuriating, and a lot of it isn't really geared for any age group at all.

That isn't to say there isn't anything useful, but it didn't feel any different than blog posts I've found that try to sell me things.
