I am one of the customer's who really disliked the changes that Audiogon made to the website. I e-mailed Tammy and within a couple of days, the "search by price" function within a brand was fixed, and they were very gracious about my comments.
Right now, the "classic" view works fine for me, and I thank Tammy and Audiogon for it. And no, I don't sell audio gear for a living. So, I hope I don't get too many posts nominating me for the "self promotion" award.
If I'm grumpy about something (like the changes to the website), I try to address the issue privately, in order to get the change I am hoping for, and avoid embarrassing somebody. It works for me.
Meanwhile, the public poster's do a great job of calling out the folks, like... say.... Michael... who wins the above-mentioned award, hands down.
Happy buying and selling.
