I do plan to buy the post and use it regardless, but it isn't a silly thing. I wish people would stop the practicality games with bicycles. All of us want our bikes to look the way we want them to look, and differences between people's approaches to appearance are a matter of degree rather than of kind.
To each his own. I care a bit about how my bike looks too but would never be bothered by something like that.
Also, if you think part of that Nitto logo is going to be inside your seat tube, maybe you should be more concerned with the possibility of having the wrong size frame. The "N" is only about 110mm from the rail position.
