I and others have posted about Web Sites. I have started at least one thread, if not 2, and contributed to others. I strongly believe in Web Sites and I think they will only grow more important in the future.
Actually, I have several sites (his voice dropped and he glanced around) because I write under several names in different genre.
I don't sell from the sites because my plate is full and I don't have the time to keep up with it and do a good job.
I don't think it hurts but I would advise doing it only if you need a break from your writing or your job and you are taking proper care of family matters.
1and1 (host) will set you up if you want to try it.
