keep on going....monitor the new directories announced on DP, vilesilencer and the like and submit to one-or-two every day-or-two...far less painful than doing 450 in 3 days.... Also build backlinks from other sites, again DP is a good place to start...
A hard working. The best way to make your site get google indexed fast is to post some of your articles to Digg like sites. I submitted to some directories, still haven't got any feedback in terms of PR and traffic. I'm not sure whether I should go more.
