I was running a report on my blog the other day for SEO and the most used word and words on my blog are seen as "Loading" and "Close" followed by "Close Preview". The reason being I use this plugin, which I love, and I load around 40 blog feeds into my sidebar. Now, I do not use the enable bookmark preview feature, I just show link title, article title and date, however the plugin draws the area for a preview none-the-less but just keeps it hidden and does not populate it.
My request is that the area for previews not be drawn at all unless the option is enabled. It's aggravating from an SEO standpoint to have an unused feature become the highest keyword density on your site. In addition, for those who do use the preview, it would be best to not default the Loading text into the div as you draw the code, or Close Preview, but to instead draw that text with jQuery as needed.
Just my humble opinion as somebody trying to clean up some SEO elements on my site.
