JRR, I didn't realise you meant a specific kind of asterisk. Yes, that makes it much more likely to be recognised. I like it.
There's also something so aspie about saying "no, not any asterisk - that asterisk". To NTs an asterisk is an asterisk, but aspies being so detail oriented may notice the different kinds. (Clearly I wasn't aspie enough yesterday.
)
The cool thing is there is even a Unicode character similar to your graphic, which means it could be used in text communication:
✻
This is the "Teardrop-Spoked Asterisk", Unicode character U+273B, HTML code
Code:
& #10043;
(without the space)

If that happens in only 5 years I would be very surprised by its success.

Anyway, yes, it would eventually happen if the symbol takes off, but I think it would still have served a useful purpose in the meanwhile. Perhaps it will serve a useful purpose even once it does become "appropriated", as it would help raise awareness of AS and may lead people to the source of the symbol - aspies themselves, not some "awareness campaigner" like Autism Speaks.
