I USE PADLET
An embeded Twitter feed works. But what if all your students aren't on Twitter? What else can you embed to allow their posts to appear on your write-protected Homepage? I'm using an Our Culinary Arts teacher is now using it for students to post their finished recipies. You can even tweet the link to the Padlet out in internet and possibly attract others to join in on discussions. I do that, but rarely get responses. But when I do, it's pretty cool!
