That post suggests modifying core WordPress files – which is a Very Bad Idea(tm).
If you don’t want display site urls in your comment list, simply create a custom comment display ising a custom callback in wp_list_comments().
I did not explore other methods, however, you’re simply commenting two lines out of a php file. I suggested backing up and using a text editor, but to mess something this simple up is actually quite hard.

Not from from what I’ve seen – especially if you’re not used to PHP. Plus you would also have to repeat the process every time you upgraded WP.
On a more general note, hacking core files can compromise your site’s security unless you really, really, know what you’re doing.
I am curious to see how commenting out those two lines would compromise site security. In any case, I looked up writing plugins and found that creating a plugin is the easiest solution since you don’t have to worry about theme or core file updates. I have updated the post explaining how to create a plugin to remove the website field.

Original question was never answered–is there a way to hide or turn/off the Website input on the WordPress User page. It is possible to hide the personal options, it is possible to hide the contact info, but getting rid of a few of these inputs (Website, specifically), is proving difficult.
