blogBuddy (http://blogbuddy.sourceforge.net) is the Windows (95/NT/ME/2000/XP) equivalent of BlogApp, providing a basic text editor with bold, italic, underline, and hyperlink buttons (see Figure 2-5), web service-based spell checking (meaning you don't need to install a big dictionary), support for multiple weblogs (but not multiple accounts), and the ability to edit previous posts and main and archive templates.
blogBuddy is open source software, distributed under the GNU Public License, downloadable as both a self-installing executable and a ZIP archive.
