I've never bought into the "SEO-friendly" domain name concept. Do "Google" "Ebay" "Yahoo" "Skype" "Flickr" etc really evoke images of what those sites are all about? Flickr comes close, but the misspelling would be kind of a nullifying effect. There are plenty of sites like Paypal that have domain names that better indicate what they do. But still, I doubt anyone googles for "how do I pay my pal electronically". Keep domain names short and at least sort-of pronounceable. The rest is content, marketing, value and luck.
