The logic of giving a witness your vote? If it weren't for witnesses, you wouldn't be able to transact on the blockchain. Perhaps you meant giving Hive account@fulltimegeek your vote? I feel that those who hold the skills to run a witness server and carry out the responsibilities of a witness, have put in the time to learn about the blockchain, and who care about the network and community, deserve a vote.

And I would hope that anybody who is considering voting anybody for witness would go check them out. This post is not his witness application, and it's certainly not his complete bio, so I would recommend doing some research on him before deciding whether he deserves your vote.
