I am with Fonz and Sponk.
Taking those short cuts do you more harm than good. Try to get your site in major directories (Dmoz, Zeal, Yahoo!) and a few on-topic regional directories.
If you manually submit the site carefully (using carefully crafted Description, submitting to the right Category, etc.) it will get listed faster. There are a lot of DMOZ clones that gobble up DMOZ generated RDF dumps at regular intervals.
Once you get in these major directories (may take time), as well as few selected regional on-topic directories,
you site will gain visibility in most major serach engines without having to auto-submit to all those zillion micro-search engines.
I am not familiar with the specifics of what
Cornel and
biggie are mentioning, so please do not take the above to be a negetive reflection of that in any way. Just trying to help, not meaning to be disrespectful to any one...
