I have made sales and boosted rankings thanks to online press releases websites. The most recent success I had was after I won a national competition which isn't well known outside my industry. I used this service to publicize that fact which lead to other outlets picking up the story and interviewing me. I wouldn't take the time to do it with boring stories.
You can do this for any industry as long as you have something that is interesting to publicize.
