I don't know why the web isn't more friendly to sub domains. We keep wasting domain names. Reusing domains and using sub domains is an elegant solution.<p>I hate going to web sites that dump every product they own on one page, along with support, company information ,etc. It just makes it harder to find info for what I want when I have to look at everything. If they had a subdomain they can dedicate what appears as a whole site to just that product. Then their company info, career portion, etc can be on their main domain, and keep it all separated.
