Social Media Day is happening on June 30 in cities across Canada

Mashable's second annual Social Media Day is a celebration of the technological advancements that enable everyone to connect with real-time information, communicate from miles apart and have their voices be heard. 

It's also a chance to chat with your online friends in an offline context.

Mashable and Meetup are being used to organize SMD celebrations across the world. In Canada, there are meetups in Vancouver and Toronto, while other cities like Waterloo, Ottawa, and Calgary may or may not end up happening (they need more attendees and planners!).

If you can't make one of the SMD celebrations, you can still follow along on Twitter by using the hashtag #SMday.
