Yes, but much less. For example, when I first heard of webmaster-talk.com and seo-talk.com, I kept typing in seotalk.com and webmastertalk.com, which led to some other unidentifiable web pages, then I was like "What is this?". So I had to check my bookmarks, and then I found out that there's indeed a dash in it.
But when I go to forums like xboxforums.net, it's not like the next day I forget and type in accidentally, xbox-forums.net. It's still possible to occur, but less likely than the other way around.
