Here's an idea I thought of a few weeks ago: Subscribing to Users on Instructables.

It will be exactly like YouTube kind of, except you can see the New Instructables/ Slideshows/ Videos any of the users you subscribed to posted.

Picture 1) This will be on each users page. Obviously the button will not be like that, it will be like the buttons on Instructables, gray and orange words.

Picture 2) Next to Submit, it will say "Subscriptions v" (v is the little arrow), and when you hover over it, it will say New Instructables, New Slideshows, New Videos.

Picture 3) Couldn't make my own, so I used YouTube. It won't be like this, but it will be close. See the New Videos/ Instructables/ Slideshows? Click on any, and it shows any of those from any user you are subscribed to. And when you click their user name, it shows all the new stuff from them. See how right now in the picture it just shows a video? Exact same thing will be for the Instructables and Slideshows, so they won't have a video time under it unless it is a video. It shows the date it was posted, the views, the ratings, the usual.

If you have any suggestions, please comment!

Thanks!
