Hi Ian,
Yes, I was really thinking about some of the applications which will work on Vista/XP/Linux etc., or where download pages contain versions for all platforms.
It occurred to me that occasionally, someone mentions an application (or software) which doesn't fall into the other categories (such as XP/Vista, or security/spyware or gaming category... such as my Shell Extensions post, which made me puzzle a bit over where to put it, before it ended-up in the General Discussion area. lol) But on the other hand... I can see your point too, that it might not be a particularly busy area.
