Using extra domain names to promote developed site

[coop99]

I believe someone asked a similar question recently about multiple domains and SEO. You can check out the suggestions here:

Search enignes will not want to see same content on different domains. They will not want you to link all your sites together "accessively." So if you host on different ip's, you can link the sites and they will count more towards your link popularity. You could also create mimi-sites on your other domains so that you can more accurately target your keywords and phrases.

There is also domain name re-selling, whice you said you did with SEDO parked pages (dont bother). You are better off getting the domains appraised and posting them in domain name forums for sale.
