If you didn't realize, Instructables' interface for viewing things has been changed for featured, popular, rating | recent, views, and zeitgeist. I saw a couple of complaints that they didn't like this change, so to everybody: here is where we change things.
Don't forget to rate if you like it!
Step 1: Viewing
First, you want to view the Instructables/ Slideshows/ Videos, right?
You obviously can't view without viewing.
Go to "Explore v" and click on one of the things that comes down in the dropdown, and pick whatever you are looking for.
Then move onto the next step when you are ready.
