I understand about indecision
But I don’t care if I get behind
People living in competition
All I want is to have my peace of mind

Avoid Indecision, Grant Peace of Mind
If you are a software designer, your goal should be to have every page have one purpose. This way you minimize user indecision, you find that the application is easier to explain, and by going through the excercise of this constraint you gain more confidence that your design achieves the primary purpose of the app.

Google Gears
Google Gears javascript libraries transparently create and update a local database. Developers simply execute SQL against a local database. Google Gears’ database module takes care of prompting the user for permission, creating the database, and executing the SQL. Google Gears also provides a local server module to cache web content and then serve it locally from the user’s disk. See The Google Gears API Developer’s Guide for details.
Simple Implementation, Complex Problem
The power of SQL calls to a lightweight, transparent, local database combined with ability to server http content locally make it appealing to dive into offline-enabling our web-apps. And Google Gears is open source to boot!
Data synchronization can become a very complex problem. Considerations for conflicts and concurrent updates must be made. Each operation must be tracked and timestamped for proper synchronization to occur.
Still, I predict that robust synchronization libraries for Google Gears will be developed. Google Gears has just been announced and is in “developer beta” now, which means it is intended for developers to start looking at and working with. Though it is not yet intended for production use, Google is using it in their feed reader product from Google Labs.

”When you begin a picture, you often make some pretty discoveries. You must be on guard against these. Destroy the thing, do it over several times. In each destroying of a beautiful discovery the artist does not really suppress it, but rather transforms it, condenses it, makes it more substantial.” – Pablo Picasso
Code that ends up not being used. Design sketches that get tossed. These are not evil things. These are not wasted work. Throwing out work is part of the work. Don’t be afraid to do it. Iterative development is a process of letting go. And letting go can be hard to do.
