I tried using RSS Digest to add links from my iBLOGthere4iM blog to the BoingBoing blog. The result was ten javascript:document.writeln("");. This was working a few months ago, but has since stopped working. I assume the RSS Digest service is not being maintained.
Update: Reviewed the problem w/ Peter Cooper of RSS Digest and we identified the problem as lack of escaping of certain characters in the javascript src attribute.
