The myth of growing your LinkedIn presence

How bad would it be to return a request for a LinkedIn connection with a simple question:

Why do you want to connect with me?

Are you going to write a recommendation for me or do something otherwise beneficial, or are you just trying to grow your network?

Does it really do you any good to grow your network if all you’re doing is building connection upon connection without ever interacting?

How effective would Facebook be for keeping in touch with family and friends if you had thousands of connections but no one ever wrote an update or sent a message?

Would it be more effective to have 1,000 connections on LinkedIn and no reviews or recommendations, or to have 100 connections with five genuine recommendations from people you truly know and have worked with?

Why do you want to connect with me?
