I think online tutorials are essential for the survival of any software package these days however 'amazing' the app may be. I learnt the old way, as many of you here I imagine, from reading through the manual, trial and error, experimentation etc. because online resources didn't exist for anyone back in the day. Expensive face to face training was the only option then.
That's all changed and If potential buyers cannot quickly evaluate a packages potential by seeing evidence of what it's capable of and how to use it they will quickly move onto the competition. The fact most of FZ's tutorials are over 7 years old is laughable and would put me off straight away if I were starting out again. I was looking to expand my own knowledge of FZ and get into more asset based modelling and sub division surfaces but became increasing frustrated at the complete lack of any meaningful tutorials. I've since moved to Modo - sure, it's a bit of a learning curve but it's been made a heck of a lot easier by using the wealth of high quality teaching material out there. I've learnt more in 3 months than I ever did in 20 years of using FormZ.
