Thanks very much for checking out the site!
I agree with you on the thin explanations. The focus of the site is
to just give examples, but being a little more verbose would probably
help many readers.
Good point about iterators too. It's a funny pattern with most
languages already having an iterator, which is why I tried to
illustrate implementing an iterator with an algorythm that wasn't just
linearly traversing the array one element at a time.
Funny you mention db normalization, I was considering doing a series
on that once I finish the php design patterns. Probably show one
example in 1st - 4th or 5th normal form. Have to come up with good
example data for that.
