Site up and Running....now what?

I've created two authority sites. Themes up and running, on site SEO is looking good. Several SEO optimized articles posted on each. Good keyword optimized domain names. Adsense going for each site, sitemaps submitted to google....

Whats the next step? Should I be blasting for backlinks at this point? What the correct course of action once the site is up and running in order to get the traffic streaming in?

Did you ping those articles, brah?

Start making your basic ring with blogger/wordpress/posterious/onsugar blah blah....

CHeck is the articles are indexed. If they are, yup you can start backlinking. Submit to article directories, create web2.0s etc..
