"AT Audiogon" "ON Audiogon" Help


Sitting in my chair responding to a fellow Audiogon member I came to a pause..... one finger on the letter "A" the other, on the "O". "What is it?" I ask myself. I need your opinions fellow members. Here's my example
"You can buy cable at Audiogon"
"You can buy cable on Audiogon"
Your votes please.

I vote for both. 'On' when your 'logged on', 'at' when directing other to it. Such as, I'm on the phone, but you can call me later at 555-0000.
I hope this isn't going to be resolved so easily. There needs to be much more debate before any resolution can be reached.
