If you’d like a tool for managing your projects, you can use this application inspired by David Allen’s GTD:

http://www.Gtdagenda.com

You can use it to manage your goals, projects and tasks, set next actions and contexts, use checklists, schedules and a calendar.
A mobile version and iCal are available too.

I agree with you. However, I think that the post above says the same things. It’s merely dissuading the reader from spending tons of time on low quality directories. The article mentions that some directories that it provides quality SEO benefits but don’t expect too much traffic. I’m making the assumption that you are using good directories with quality exposure. Is that correct?

Perhaps you disagree with the point that says that you shouldn’t expect a large increase in traffic? I’ll admit that directories give targeted traffic, but perhaps you can share how much traffic you gained and how you went about getting traffic from directories.

Using my own sites and client sites I have been able to not only increase traffic to a site using Directories but sales have increased significantly.

If I had to pick only one method, directories would be it.
