Google Docs 'Edit HTML'

I've been editing my CV on Google Docs for a while and now I'm trying to get it in to a format (PDF/RDF/ODF) to send it on and I seem to be having a lot of problems with white space. I get very large gaps between paragraphs that I'm just not expecting.

To find out what was going on I have tried the 'Edit HTML' function and can see the problem...lots empty paragraphs, spans and H3 tags. So let the hacking commence.

I'm surprised with the way Google are representing documents, lots of font tags and style attributes on elements. I was expecting greater use of CSS. Surely this would allow greater control over the available styles and make them much more powerful whilst making it easier to convert to all the output formats?
