actually I think I may have been confused with what you said, you want to share knowledge of usage of DAWs? what kind of usage, recording or mixing or composition or all rounder?
I believe everyone should learn abit of recording because inspiration strikes when you have the least capability of remembering it. and this applies well to potential great songwriters/musicians/guys who're playing in bands. so they can do their own "preproduction" before they hit the studios.
but when it comes to the topic of mixing ,I feel there's a high chance of creating a spoonfeed "preset" nation of new home producers who just want to learn mixing for the sake of saving costs of recording their own band. so it's a materialistic application for their real passion (band) rather than having the real drive/commitment for the "art of sound".
http://soft.com.sg/forum/how-sound/132437-creating-space-mixing-2.html is a great example of how one question can show an entire display of so many different perspectives/self-tested,experienced methods yet it will never be a One-Final-True-answer to the threadstarter's question, because they're all merely guides/tips and hints for the threadstarter to EXPERIENCE,TRIAL and ERROR for himself if he wants to improve.
So there's only 2 ways to learn, the "easier" way, the hard way. and "easier" way has already been a longtime paved path by the very people who created "presets" found in software to hardwares like UAD/powercore etc. The hard way would be through experience and I'm very sure everyone of us here have their own story to tell and nothing beats that. oh and before I forget, a "tyco"(lucky) way, you get to meet someone who is willing to teach you his trade secrets.
to give my response to the idea : it is very enthusiastic, people who are new (term noobs will be arrogant) will prob hate me for the "preset nation" remark , people (who know what i'm talking about) will agree with me if they can see my view. But I'm the sort of guy who'd rather donate $1000 to 1 than to split $1000 with 1000 people based on impact measurement. but this is if you're referring to "Mixing".
If it's for "Recording" or "DAW familiarising" then it'll be definitely great to showcase capabilities of different DAWs and draw a final suitable balance for the consumer to "pick his weapon" to suit his OS and preference. Also to help people who have already chosen a DAW to have a better understanding of how other people use it or get to meet other producers who are using a similar DAW and communicate/share as a big family.
But my preference would be more forum based (like my DIY recording FAQ) because running a "workshop-like" thing kinda cost cash/time to prepare. and not everyone will make it. it'll probably be easier to run it on a video like SOFT TV/youtube. Not everyone can make it for a SOFT event in real life, but when it's on the forum/youtube, everyone checks it out during their working office hours lol.
I'll see how's the response for the other OS/DAW guys before I join in the fun... cos I personally have a couple of young interns to take care of.
