I often read stories about how great LinkedIn is but I've never heard of anyone who actually uses it saying anything good about it. Everyone I know signs up for it and then doesn't use it for anything. I especially hate it because I keep getting invites to join from people who I just happen to be in their address book. LinkedIn, in my opinion, is nothing more than a giant SPAM site and I'm sick of their invites. I have never used LinkedIn and I would never use it either because they have created a horrible impression with all their intrusive invites. Maybe I'm missing something? Anyone have a positive experience using it? When people ask me for my email address, I now ask them "Do you use or do you plan to use LinkedIn? If yes, then no you can't have my email".
