An idea for the ever increasing "Show Off" 'ibles.
What I am suggesting is a topic at the top of the website, (next to the create,explore,contest,community,search), named "Show Room". Where people who do not currently have a proper instructable, but still want to display their creations. Could also be used by people currently working on their instructables as a "Heads up on what's coming".
This would clear out the 'ibles section quite a bit and give the site as a whole, a more organized feel.
Those are my 2 cents. Love the site, wish to see it grow even more!
