Happy Social Media Day!

What’s that? You didn’t know today was a holiday?

No worries. I’ve collected some news about today’s celebration, as well as some ways I think you can mark the day.

First of all — a quick definition. Mashable (my very favorite resource for social media and technology news) sponsors Social Media Day to celebrate what it calls the “revolution of media becoming social.”

People all over the country are taking part, both in person and online. Here’s a collection of some of the fun ways you can follow the celebration:

Follow @mashSMday on Twitter

Follow the #SMday hashtag on Twitter

Find one of the local Social Media Day pages on Facebook

Find a local Social Media Day meetup on Meetup.com

Watch the live stream of Social Media Day celebrations all over the world

Track photos shared on Instagram with the tag “SMDay”

And there are some really cool projects already in the works…
