I think they have a use.
For instance, a lot of late diagnosed people come across them, more than anything to see if there is much reason to pursue it further. Autism testing can be expensive and have long waiting lists, and for an adult trying to figure it out on their own, very highly stressful.
They simply shouldn't be used as an end all be all. Taken with a grain of salt. Plus the aspie quiz is kinda cool with how they break everything up.
