Lesson for LinkedIn: You need to communicate the value of this feature more effectively to users.
Lesson for businesses: Nobody wants to read your ads. People may tolerate it if they’re receiving other valuable content from you. But LinkedIn doesn’t (yet) have the kind of conversational engagement that Facebook or Twitter has, so you’ve got to carefully consider what you’re putting in your LinkedIn stream. What will truly be of interest and value to your customers and potential customers?
Lesson for users: Look before you link. What kind of content is this company publishing? Will it create any real value for you, or just more infoglut? I see a place for it, but I recommend using it sparingly. The burden is on the company to engage you.
