It isn't enough to just produce content and publish it. You have to spread the word, and promote it. Socialbookmarking and rss feed is more important than ever. You can go in and socialbookmark your marketing efforts yourself, but at some point it will be obvious it is you promoting your site, and in some cases even if you have multiple profiles your ip address will be associated, and you will get shut down on some bookmarking sites. To go in manually and do this would take hours. My first recommendation is to outsource it to a qualified company. If you can't afford to do that, the next best thing is to use the highly recommended socialbot.org, and rssbot. It is a inexpensive software that you download to your PC. For us MAC users, hopefully a solution will be on it's way.
