Comments are a terrific way to get involved in online discussions. They also help promote your own blog or Web site.
The pro-tobacco lobby utilizes comments to the extreme. When you visit stories about clean air acts, secondhand smoke and the like, many times you will find comments about how the data is flawed, civil rights are being violated, etc. Sometimes, you will find different users posting the exact same comments - which means their network creates a list of approved comments for all users to post everywhere.
Advocates for clean air can be much more creative about it. When you leave a comment, make sure it has meaning. Offer something new to the discussion, ask follow up questions of the author, respond to someone else's comment. The possibilities are endless. Be creative - and do NOT leave a "canned" response - those are considered spam by many online users.
Sites have different requirements for leaving comments. Sometimes, you will need to sign up for a site-exclusive account - particularly on newspaper Web sites. Many blogs allow you to use your blog account, or Open ID, so you don't have to create anything new. Other sites allow you to post comments anonymously or allow you to simply insert your name, email (never published) and Web site and comment without any fuss.
Caroline Middlebrook has a good post about the proper ways to leave comments - with a list of comments that don't work. Be sure to read some of the comments at the end of the post. ProBlogger has a terrific post about how comments can benefit your online presence.
