Journler
To add content to this Blog, I am now using Journler, By Philip Dow, as my primary writing tool. Journler has a great writing environment and sophisticated tools that I need, such as tagging, organizing content by categories, custom labels, and a pretty good search engine.
I also like the default font that Journler uses: Cochin Regular 14n. However, sometimes I'll switch to Georgia Regular 14. If you use any Journal tool, try using Cochin or Georgia. When writing code I find that Monaco Regular 9 is better font to use, this is due to using BBEdit so much.
I still use TextMate to clean the code prior to going live since it has excellent HTML tools such as Google linking capabilities and entities converter. TextMate has quickly become an important part of my application development.
My day-to-day note-taking tool is still DEVONThink. I use this to store my source code examples and code references. All my personal and business documents are stored in Journler. This decoupling my personal life from my work life.
If your undecided between various Journal/Notetaking applications, I would encourage you to consider using more than one application. Consider one application for you business needs and one for your personal needs.
