ZMag's Digital Publishing's Seven

A print promotion in eContent magazine features "Seven Things You Should Know About Digital Publishing." The vendor, zmags, offers these:

1. Cost effective but doesn't replace print
2. Online versions encourage loyalty
3. Digital issues extends reader scope (SEO), tell-a-friend, social nets
   
4. Connect online catalogs to online stores
5. Learn what catches reader attention
6. Short ROI
   
7. Easy to use
