These days there are so many good blogging tools it’s hard to know which one to use. But there are three that are worth mentioning.
Qumana: a blog editor that allows you to use their adservice, too! Of the three tools I like, it’s the ONLY one available as a cross-platform blog editor!
BlogDesk: a simpler tool that I use for most blogging that I do. Unfortunately, it’s not compatible with Blogger at all. WordPress and Movable Type are fine.
LiveWriter: Of course, my favorite application is LiveWriter because it seems to be the most powerful. Unfortunately it isn’t supported on older installations of XP.
And for those who like integrated applications: Flock, which includes a browser, social media tools, and a blog editor in one package.
