I saw this in a forum and want some positive feedback from everyone. Is it worth it?

"If a person is willing to do these manually - submitting to web directories.

Why not go to yahoo and create say, 50 yahoogroups, add your link on the home page and edit the email template with your links on them. Advertise the yahoogroups and before long you'll have hundreds if not thousands of people joining those lists and for every person that sends out an email, your links will be in the email too. Best way to get free traffic."
