I can't praise this program enough: it's small, fast (at least now with the latest version), (beer-)free and does what it does extremely well. Also I think it's extremely generous of Brent Simmons (the author) to make a full-feature lite version for free. (The difference between the lite and the full version is that the full version can also edit and post blog entries - but since COREBlog doesn't support any Blogger APIs (yet) and since I'm quite happy with using XMLMinds XHTML-mode the lite version is just fine for me.)
