I have to give a presentation to a group of middle school students, and the activity I have planned is to have them start their own blog. Ideally, I'd like to have them set up a Tumblr account because it is easy and straightforward.

However, the pr0n. I'd rather not be the one to introduce anyone to that ecosphere if I can help it.

Thoughts? Is there an alternative to Tumblr that has more stringent content requirements, but is as simple to use?

Ever thought about Medium? I haven't used it myself, but I've heard good things.

I have, and right now it seems to have a very journalistic slant to it. It might work.

I signed my son up with Jux.com. It looks great out of the box on desktop and mobile and is pretty straight forward,

I was just looking at that. It does look pretty nice. I'll have to research it a bit more. Hate to have a hundred parents calling/emailing me because I overlooked something obvious.

How is it working for your son?

Blogger is a good option.
