A Thanks for following me twitter bot using ruby

if you have any comments please let me know.

#!/usr/bin/env ruby
require 'Twitter'
# Create a read write application from : 
# https://apps.twitter.com
# authenticate it for your account
# fill in the following
config = {consumer_key:        '',  consumer_secret:     '',
          access_token:        '',  access_token_secret: ''}
me = 'Blaze Boy' # to prevent DM yourself

Thread.new do
  loop do
    begin

      rClient = Twitter::REST::Client.new config
      sClient = Twitter::Streaming::Client.new(config)
      sClient.user do |object|
        if object.is_a? Twitter::Streaming::Event and object.name==:follow
          user = object.source
          if user.name != me
            rClient.create_direct_message user, "Thanks for following me #{user.name} :)"
            puts "New follower : #{object.source.name}"
          end
