Automated Submission Programs - Anyone have any experience?

Tweet

I have bought a program that submits my websites to directory sites semi-automatically. Too early yet to see how effective it is. I have now found a program that automatically generates multiple accounts in 100 Social Networking sites and automatically bookmarks every one of these every time you press a button on your tool bar, with randomisation, etc etc. Has anyone any experience using this kind of program, good or bad?
