I sometimes learn a few tricks from wordpress blog tutorial sites and its great that some of the people in this field , share what they know about working around with coding around wordpress.
Im just wondering do some of you know blog sites that are catering quality wordpress tutorial posts (like working around in the API, theme development , plugin development , articles) .
I know.... there are thousands of them, so I wanted to know if you have list of the best sites so far you know that do this. Probably the sites you bookmarked and visit regularly.
any suggestions will be cool
