New Sites does not have a built-in commenting system at this time. Use of a Google Form and Spreadsheet is demonstrated here as a workaround.
Feel free to use this form to send comment, but if you need help please use the help forum: https://productforums.google.com/forum/#!forum/sites
Remember to send feedback to the developers by using the 3-dot icon at the top-right while in edit mode.
You may want to call it a "Contact me" form. Whatever you use it for, when someone submits the form you get notified, then you access the associated spreadsheet to read the submission content or if you want to you can embed the spreadsheet in your page as I have done here.
See Steegle's instructions which includes a video tutorial and a method to display the most recent comment first.

Monitor this page for changes Copy the page's URL first. https://sites.google.com/view/newsitestesting/comments
Note that if you hover over the form or the spreadsheet a pop-out icon appears. It is not necessary to click this as you can fill out the form directly on this site. If you do pop out the form or spreadsheet you will see a link to request to edit it. Please do not do that.
Steps I used to make this Contact Form
- Under Google Docs, Click Create New.
- Select Form.
- Create the form questions that you want.
- Click RESPONSES and click the spreadsheet icon.
- A spreadsheet will be created that will store the form responses. Open that spreadsheet, Click the Tools menu and select "Notification rules...".
- Create a rule. Under "Notify me at [your address] when..." put a check in "A user submits a form" and either "Email - daily digest" or "Email - right away".
- Save the rule.
- Go to your site and on the page where you want the form. In the Insert menu click Forms in the Google Docs section.
- Select the form you just created.
- Save the page.
Notice that under step 6 you will be notified that someone has submitted your form, and then you have to open up the spreadsheet to see what they entered.
If you want to use this as a comment form where the comments are posted on your site click Share while editing the spreadsheet and select to share it to the public and on the File menu select Publish to the Web and to automatically re-publish when changed** and click Publish as a web page. Insert the spreadsheet itself as shown below. In the INSERT menu select Sheets in the Google Docs section and select the spreadsheet associated with your form.
Note that the spreadsheet will not automatically update. A viewer will have to refresh the page in order to see new comments and there may be a delay of up to 5 minutes before the new comment appears.
Also if you want to remove the formatting that new forms has added you can revert to the old version as I have done. See this forum post for help on doing that.
**If you want to moderate the comments do not select automatically re-publish, When you get notified someone has posted you can the publish it. File, Publish to the web, Republish now.
