user65: From the official Arduino site:

Arduino Day is a worldwide celebration of Arduino’s first 10 years. It's 24 hours full of events – both official and independent, anywhere around the world – where people interested in Arduino can meet, share their experiences, and learn more.
Who can participate?
Arduino invites all Arduino user groups, makerspaces, hackerspaces, fablabs, associations, teachers, pros, and newbies to participate. Let’s make this the biggest birthday party yet!

Arduino Day is on the 29th of March. What can we do to join in on the worldwide event?

user220: Kickoff of the Blog / Project of the month?
This is similar to AsheeshR's answer. With this we might be able to:

Generate new visitors
Gain network-wide attention (possibly)
Generate much quality content (in one post, I know)
Rally excitement for our site from the current users.

It seems like a great way to celebrate Arduino's 10th anniversary.

user65: 
Project Showoff Day/Week!

Arduino hackers are almost always working on creating something interesting. Lets have an event inviting users to post pictures and descriptions of their coolest  projects, and we could drool over discuss them. 
To participate, the user must post:

Atleast one picture (necessary)
Video link on Youtube (optional)
Aim of the project
Basic breakdown of components
Short description or video^ of working

The projects can be anything but must utilise an Arduino board. 

This could be done on either main, meta or chat. After a discussion with Peter, we are leaning towards holding this on a single question on main.
The timeline could also be longer, encompassing a week starting from 23th and culminating on 29th.
