I started a similar thread about a month ago. Suggesting funds be put in a multisig address of 3 people.
Matt608 was the only one who responded positively AFAIK. Toast suggested I start out with a lower paid delegate. (Which thinking about it some more, with price feeds etc I can understand that suggestion but meh it complicates the whole issue) Anyway, seeing the lack of community support and realizing I was just setting myself up to be committed to another half-baked project I deleted the thread. I have enough half-baked projects - thank you!
It does seem to me that marketing could use a general funds account to be used by any project. I would suggest that the multi-sig holders be in charge of deciding where the money would go. 2/3 would protect everyone involved.
