Which term best reflects the degree/ style/ of learning? If you read a book, but never talk about it, have you learned any less?

I love this list – I wish I’d come across it before I wrote my #ocTEL Week 1 post – “lurking, moderate(ly), memorable” . Thanks for all the interesting links and posts on this site. A great resource for a quiet participant like me!
