2 popular personal productivity software programs which are FREE and online (see web 3.0) are:

1. Zirrus
2. Remember The Milk

Which is better? Which do I use and recommend?

Both use the principles of Getting Things Done (GTD), but one is extremely simple, and the other is more 'advanced'.

If you have read my free report on how to have a natural time management system, then you know I'm not a fan of 'advanced' personal productivity software.
