LinkedIn - Hello

I use LinkedIn.

Where is LinkedIn's customer service?

I have sent an email every day for the past week to LinkedIn's customer service and have not received an answer. Not even an autoresponder.

"But Jack.. LinkedIn is free, how can you expect them to scale support and actually make any money?"

The value of the application is in subscriber numbers. The more subscribers, the greater value the application.

Each subscriber has a unique content page. Each unique content page has a number of ads.

There are millions of user created content pages each potentially generating small amounts of ad revenue every month for LinkedIn.

Multiply this number times the number of subscribers and you have a working example of the long tail.

This is one weakness for Web 2.0 companies - customer service. If users cannot use the application, they move on. The circle does not hold, the ends fall apart. The application unravels.
LinkedIn - please answer my email. Thank you.
