Because of the large time that it may take for a new site to start ranking (sandbox) it is important to let the search engines know about your web site as soon as possible (especially Google).
Before I even start writing content or designing a new site I always submit it to the big 3 search engines so that they can start a trust timer for my site.

i never submit; a site will (apparently) always be indexed regardless. making a site live during its development stage achieves the same effect imo.
