Yes, I feel the same and I think it is a fairly common thing for people with AS.
I feel forum and things that work in an analogue way (mailing lists, website comments, up to a point facebook status/comments, etc.) is the only form of communication that is almost natural to me.
For E-mails, letters and other forms of asynchronous personal communication it depends on the content and topic but they are globally OK too. I hate voice messages but it is mostly because I think recording them and listening to them is a tremendous waste of time while you could just send a text.
Telephone is bad, in-person interaction is worse, and video is maybe the worst of all.
Of course it depends on persons and circumstances too. (Often in an unpredictable way :/)
