I just noticed that some html tags aren't rendered properly on feedburner rss. These tags: strong, b, em, img.
the img tags also isn't properly handled by pligg.
(pligg 2.0) Links module conflicts with other features like html enabled img or a tag. When you enable links module to convert any http to links and also enable html tags for image or links (img or a), you will see that the latter doesn't work properly.
