On the topic of the now-ubiquitous slideshow, we felt compelled to showcase, in our second ever slideshow, our four favorite slideshows on slideshare. Our first selection is the ultimate, be-all-end-all guide to “Getting Your Users to Actually Use Your Product so You Can Sell It,” brought to you by KISSmetrics, that includes important facts such as “Activation is the key” and “deliver on the value that you promised.” In third, uploaded by SOAP Presentations, is “10 Presentation Facts You Should Know,” to help people who make presentations for a living make more presentations. Finally, Desk.com presents their “Principles of Customer WOW,” which brings to light brand new marketing principles like “customer service is IMPORTANT.”
