To whatever degree you find firsthand reports from autistics useful (and we are able to introspect and such, just in case your reading had led you to believe otherwise - there are some ridiculous misconceptions out there), those are a thing you can look for.

Wrongplanet.net is large, but has had some unpleasant evaporative cooling going on for several years - it may still be a useful place to ask questions. Similarly, reddit has a subreddit for autistics, but the demographic there is affected by the overall tone of the site.

Private blogs are a better bet for thoughtful information - Urocyon has a list of neurodiversity and disability blogs in her sidebar that seems like a decent starting point for that. Also, tumblr has a fairly good autistic community - we tend to post in the actuallyautistic tag, which you shouldn't post in as you're not actually autistic; you can post questions to the autism or autistic tags, and there's a very good chance we'll see them and respond. (Do your research first, though; the standard reaction to uninformed mistakes is derision here just as much as it would be anywhere else. Also, person-first language tends to go over poorly; it's a point of etiquette in the community that we should be referred to as autistics or autistic people rather than people with autism, though you'll occasionally run into individuals who prefer the opposite and that should be respected too.)
