Its a very cool widget to use on the blog. Its called WP greet box. Whenever a visitor visits your blog the first time from sites like Google, Yahoo, Facebook etc it will appear where you have placed. You can see the screen shot below.
Actually I have this widget installed on my blog above the post area.
