grantism

When I first started out as a web developer (about 8 years ago now), there were literally millions of sites and books to teach me 'beginners X' or 'Y for dummies'.

Then I got beyond the beginner stage and struggled to find any useful resources that didn't assume I was an expert and already.

Even for things that are meant to be step by step guides I sometimes find that they assume that I already know how to perform some non trivial step and breeze over it. Obviously I then go searching to find out what I'm meant to do but there's often little to no meaningful explanations to be found.

So I ask this: Why are there so few resources targeted at bridging the gap between beginner and advanced level skill sets?

OR

am I just not very good at using the internet?
