I do not agree with the advice to not submit your site to search engines. Certainly, content is important, seo is important, etc. and it is true that search engines will find your site eventually if you don't submit it, but it only takes a minute to submit the site to the major SEs, so why not do it?
If you upload a website onto a hosting server and do not link to it yourself from any other website, how will anybody else find it to link to it and if no-one is linking to your new site, how will the SEs find it? Maybe they will, eventually, but you might as well help them along, as it takes so little time. I always submit using www.Addme.com
Easy, simple, and very quick.
