Please use valid, semantic markup.
The list of links is using a fieldset with legend. However, these should only be used inside forms. I have to re-write the code everytime I use zemanta links. I remove the fieldset and change the legend to an h3.
I'd also prefer the option of no inline CSS styles on links. Not to mention the target="_new".
To summarize.
1. Don't use invalid code (fieldset/legend without a form)
2. Give us an option to have plain markup instead of the inline styles and such.
