It seems that diaspora is formatting their messages in a special way:
"... die sie kriegen können ([siehe auch](https://blog.fefe.de/?ts=b595b908
)), aber jetzt mit dem ..."
That means that the description of a link is between [ and ] and the url is between ( and ) where some characters are escaped (for example "_").
Is there a plugin that can decode these postings so that they are looking good?
