Personalize your LinkedIn invitations

I recieve many LinkedIn invitations from people I don't know that simply contain the standard text provided by LinkedIn, "Since you are a person I trust, I wanted to invite you to join my network on LinkedIn." This invitation doesn't make any sense if I don't know you. How can you trust me if we have never met? I like to build constructive relationships and believe this activity requires authenticity. Standard introductions do not reflect authenticity.
