In theory, a dating site for people with ASDs is a good idea.
From my past experience & recent things I've read here in WP forum,
Aspie Affection is not really functional (hasn't been for many years), on a technological level.
It's not maintained, glitches and complaints aren't repaired/addressed/replied to.
Have gotten search results for sites where people with disabilities and/or mental differences can find each other/someone.
But haven't ventured into them to see if any have enough population to make it useful, esp. if one isn't living in large city.
I use 2 or 3 dating sites online.
It's not an easy process, but has higher rate of allowing me to meet new people
than waiting in the grocery checkout line for some magic social interaction to happen out of the blue.
