ya.. no. I also thought it was cool when I reggae'd SelfDrivingATV... didn't color in the lines. didn't believe in the box. 1 year later, didn't renew it and wasted like $3 :D.
You can go for autono domains, yes. But why choose that when you can choose domains that already have a probable market?
Anyway, you asked for my opinion. And that's what it is. I asked for a link showing "autono" slang usage. Please show. Otherwise, if it's totally never been used before, then imo, it's not good to reggae autono names.
