CTgreen, why do say it's important to not use -'s? -'s do not effect your optimization with Google while the only main contributing factor is the amount of information on each domain you have - which I've found doesn't matter to the point of not needing to worry about it. You can have whatever domain name you want, and still advertise something. I can understand the relevancy of your domain being important to your subject matter, but as long as it defines what your product is (with or without -'s), I really don't see why it would matter. I've found that add -'s to something, especially if it has 4 or more words, makes it easier to actually read what your domain says.

I think the important thing to make sure of is what you actually have on your website. If you have a website with awesome content, highly relevant & detailed information about various products, and other important information - I honestly don't think they're going to care whether you have a couple -'s in your domain name or not, especially only being your sub-domain and not your primary.

CTgreen, if you backed up with what you were saying with reasons why one shouldn't use hyphens, perhaps then I might be able to follow. If you could elaborate, would appreciate it buddy.

the-digital-picture.com is one of the best websites on the web for new digital camera reviews... and it's got hyphens :-)
