Padlet is a blogging tool designed for sharing and collaboration. The manufacturers describe it as a 'blank piece of paper' that you can add content to (e.g. video, images, attachments, comments). It can be used on iPhones (there is a specific app) and is otherwise web based.

I've seen it used as an online tool for gathering comments/ideas about a particular topic but I have never personally used it for blogging.

You can easily set up a free basic account at:

https://padlet.com

Or otherwise you can upgrade to a paid account for a small fee.

This is an example Padlet that I put together in a few minutes:

It can take a while to load video clips (especially if they are quite long) but it seems to handle most formats fine.

I've chosen to make this Padlet accessible via a link and to give viewers editing rights but you can change this to make it more or less private and to increase or decrease the permissions.
