Social Media vs Profile Seats
Social Media Platforms vs. Business Profile Sites
Working on strategy for Completed.com I have spent a lot of time studying other services. Viadeo is an interesting one. There are a lot of interesting models out there. One way to look at them is from the perspective of user acquisition. Sites like Facebook and later LinkedIn got very good at network effect. Profile sites often have to rely on organic search and other traffic sources. This seems to be an inherent disadvantage. In general, models that rely upon organic traffic sources other than network effect seem to have a maximum potential.
