Balls!
AW is, by a dozen country miles, the best resource there is. It has many limitations and annoying quirks; it could certainly use a big dose of fresh innovation and all-round improvement, but the competition is... utter dross.
Most complaints about AW are remedied by visiting VivaStreet, Gumtree, AceMassage(!?), or being restricted to agencies, all of which are even more vulnerable to dead-links, false ads, B&S etc, and most make the user search experience even more cumbersome. And searching for Indies without the benefit of a marketplace platform is impossibly time-consuming.
Whingers are free to write to AW with their constructive suggestions, or show us all the how it should be done and fund their alternatives.
