I could not agree more. Trying to "game" the system is a really bad idea with Google. The only thing worse than not being on page one of Google is not being on Google at all!!
Having said that, I have had a lot of success by having my clients post relevant and meaningful information on blog sites and having those sites link back to their sites. This is a very effective technique and is not "gaming" Google.
A number of my clients are attorneys. Getting an attorney to show up on page one for a search like "Dallas attorney" is much more difficult than "Uri Geller Biography". Creating content on popular sites and linking that back to your site works!
Damain raises great points and gives some great advice (especially on choosing a good domain name). One point that he raises that I had not considered was the "nofollow" tag. If the magic sites that you post to include the "nofollow" tag (as this one does) then find a site that will accept an article from you. There are many sites that are looking for content. Find a few and write some articles for them.
