Not to be the naysayer, but how do we keep the list of detailers current? People leave the forum / quit business all the time. Nothing more frustrating than 'link rot'.
Second question...What standards are used to ensure the people on the list are not "DISO Divas"? IMO there's a bit of an implied guarantee if AG has a list of "pros" on their forum.
Third...without some kind of an AG Guarantee that you can trust your car to someone on their list, what benefit does the list have over phone book/google/local advertising that detailers can do?
Interesting concept, but not sold on the idea.
