What does the software or service do well? Very easy to use and well priced. Easy to add a backlink and perfect for getting something published quickly. Also very much like the fact that the article can be edited again at any time.
What does the software or service not do well? Not the biggest press release site but I'm sure it will continue to grow. Worth supporting.
What do you wish you had known about the software or service before using? Quite straight forward.
Have you used a competitor to the software or service? If so, how does it compare? Simpler and faster than some of the bigger providers. And you can just publish a single press release without needing to sign up for a long-term account.
