The change I've noticed with affiliate reps if you compare them to 1998 is that now, their only focus is on making you sign up and trying to get their numbers

They are all friendly and helpful to do just that but as soon as you have some more in depth questions like can i link to a product / model page it takes days (if even) I get an answer

This is in general but for the most programs its true.

Most of them also lack a mini guide and just offer links and banners and what more
