I recently started a new Max/Technology blog on which i have been posting various articles on useful pieces of max msp jitter knowledge that might be useful for absolute beginners as well as more seasoned users interested in finding odd tips that they may not currently be aware of. The blog itself is half aimed at helping others as much as acting as repository for little things eg. expressions, structures and methods i sometimes try to use and forget how to so the topics discussed don't necessarily follow any particular tutorial structure. I've been using Max for about 5 years now but i don't pretend to be any kind of authority on the matter so if you find mistakes please feel free to let me know because it'll be as useful to me as it will to other people.
Hopefully someone finds it useful.
