Thanks for the feedback. It appears LinkedIn in WildFire stopped working sometime between yesterday morning and Friday last week.
I suspect that the LinkedIn API has changed the URL of the status service. It is possible that it is a temporary problem and will start working again. I have not seen any notice on the LinkedIn site that they would be removing support for the existing URL.
I'll keep an eye on it, and if the LinkedIn API stays this way then a new build of WildFire will be required to address the problem.
