Videos would be great, however, examples which are more practical would be even better. All too often I've found that the examples in most books hardly ever relate to a situation you'd encounter in your job! A brief blurb at the end of each section named "Laymans Terms" would also be ideal. What did the chapter you just read really mean? It should be written in a manner that if you had to explain it to a coworker, they'd understand it and think "oh yeah, that made sense"

Setting up transactional replication for example. Reading a book in that was helpful but the gotchas that occur in real life usage is not really mentioned (like what automagically happens when you add a new article to an existing publication in an OLTP system - and SQL decides to take a brand new snapshot of the entire publication, locking each table as it bcps out the data to the network). All I can say is THANK GOD for this website 🙂
