First the good things, it has a spell check (I need a spell check) and it makes linking easy.

Now the things that I really really hate about it. First it ends every paragraph with a line break. Yup, <br /></p>.

However, there is much much worse to come, hit Ctrl+i and you would expect to go into italics mode. HTML has two element that could fit the bill. <i>, the italic element, and the element that most people mean when they use <i>, <em>. Which does Mozilla choose to use? Neither, instead we get the bloated <span style="font-style: italic;">.

While I've a great advocate of using CSS in favour of <i>, using a span with inline style is rather missing the point. Use a useful class name and an external style sheet, but don't use a dozen times the bandwidth for no advantage.

Anyway, back to Danny's problem. Nvu is a fork of Mozilla Composer with added site management features. Maybe they've even fixed the issues with bad markup.
