Every morning I load up a script that posts every 30 minutes, 12 hours a day. Takes 5 minutes, but I could choose to have that script pull from a recursive file and never attend it at all.
I also include ads from my site advertisers. This enriches ad campaigns and increases sales. Branding reach has also increased significantly.
In less than 1 year I have well over 15k Twitter followers. I follow no one.
