Dan,
I think your desire to keep things as open and public as possible is a noble gesture to avoid some of the 'in fighting' that can happen around such ventures.
As I said on the Worden WMAC forum, I think it should be remembered that this whole project is still very much in its infancy and at a 'brainstorming phase.' I think before people start getting too quick to take offence at who is or is not on the list it should be remembered that there will be many changes and revisions before the final decisions are made about every aspect of this event. Making suggestions with rationale is one thing, open accusations of slights and 'not invitiations' as disrespect should probably be reserved for the moment IMO. I don't think that it is nearly as hostile here as in other places.
Personally, if the 'barking dog' types don't think you are doing it right, let them take up the task of organizing their own event that fits their vision instead of putting up obstacles in your way. It's your ball Dan; "Run Forest, RUN!!!"
Question for you though:
Do you have any 'revelations' or 'wow' observations that you never expected to have based on the reactions you have seen or had to deal with directly so far?
Believe me, I will understand if you want to reserve answering for a little while if this is still too overwhelming to really form a thought about at this point.
