LinkedIn continues to develop and improve the Company Page exerience, as well as integrate SlideShare into their platform. Businesses with a LinkedIn Company Page can now share images or files as a status update, not just text and links. The file sharing functionality in particular is interesting since a presentation or PDF that is uploaded will be automatically converted and displayed.
Earlier I uploaded a new eBook I created called Creating Great Content. It's a free eBook and being able to share that with my LinkedIn followers directly is an excellent marketing tool.
