Autistic boy writes blog

There was this book i read in i think middle school, about this boy who i think was autistic, and wrote stories on this creative writing blog every day- and he met a girl who commented on his stories and he met her at a convention for this blog? i cant remember the name of it but i think thats what happened- it was obviously fiction made for young adults or kids, so no NSFW or adult stuff. it was middle school or freshman year i read this in. Please help remind me of the title of this book so i can read it again

Almost certainly Anything But Typical by Nora Raleigh Baskin.

I came across an article in our local paper about The Reason I Jump written by an autistic person, but I don't know if it fits any other details.

The above book is probably the one you're looking for, but I also want to share another famous book:

Carly's Voice: Breaking Through Autism by Arthur Fleischmann with Carly Fleischmann
