Nowadays people use validators very frequently on websites where anyone can leave comments, as in the above example.

In the previous exercise, we saw how to leave a comment on a weblog. This is one of the most powerful uses of blogs—someone posts about a subject you're interested in, then you leave a comment on that post, and later the owner of that post answers you back with another comment. If you leave your e-mail, both can establish a two-way communication! With Apache Roller and this book, you'll learn how to make blogs and interact with other blog owners in the ever-expanding blogosphere universe.
At the time of writing this book, a lot of companies are already using blogs to promote their products and services. There are employees from several companies who use internal blogs to communicate with other employees, and external blogs to communicate with clients, potential clients, and anyone who's interested in their professional activities, or even their hobbies. The beauty of it is that you can mix posts of your activities at work, along with posts of your hobbies and personal interests. Moreover, if someone has the same hobby as yours, he/she will be attracted to your blog. He/She will also see the other posts you have, including any promotional message about your professional activities, the company you work in, or your small business. The possibilities with this type of "free advertising" are endless.
