The site till now has had only 206 updates from users. With lots of more holidays and Christmas coming soon it is sure to overflow with some real cool updates to look out for. It’’’ be interesting to see how Twitter and You In? counters each other if this campaign takes off in a massive way.

Here is how Yahoo puts it:

“ Help us create a ripple of good around the world with purple acts of kindness. Update your status to share what you're doing to spread holiday joy, then inspire others to join you by asking, "You in?"

Yahoo! will also be doing our own purple acts of kindness inspired by your updates. So whether you pay for someone's groceries or drop off a coat for the homeless, you'll be encouraging people around the world to join in acts of kindness.”
