Creating a PDF file out of your scanned resume is fine, but a visual creative resume would be more effective and appealing. Everyone out there is talented in some field or the other, but only those with creativity will stand out. LinkedIn is the only professional social network where people update their professional bio which includes details like "Education, Skills, Achievements, Awards, Projects, Job positions, particular Expertise and most important Recommendations ..."
Creating an e-resume is important enough just like a hard copy. There are multiple online sites which ask users to fill up forms, and finally create a PDF or an e-copy of your resume using a suitable template. That's good enough but not creative. Pictures convey more than words. So how about creating an infographic (information + graphics) ?? Visual.ly is a site that lets you create a visual resume using available information from your LinkedIn profile. Here's what I created from my LinkedIn profile:
