From the website:
So, what exactly does being a participant entail? First and foremost, you'll be able to celebrate and participate in an event that happens each year in New York City, Book Expo America, from the comfort of your very own home, hopefully a snugly armchair! Secondly, and we hope equally as important, you'll be able to meet new book bloggers and join together in a celebration of the wonderful community that comes out of book blogging. Lastly, it means participating, however you're able to. This can be by posting, tweeting, discussing, or even by simply reading and commenting on participating blogs. Your level of participation is entirely up to you, but we hope you'll find something to get you involved in this fabulous event!
Just as the real BEA in New York, Armchair BEA will run from Monday, May 23rd through Friday, May 27th.
Some of the activities are:
Daily Theme Posts
Interviews with Another Book Blogger
Vlogs Direct from the actual BEA Event in NYC
Giveaways: At the Armchair BEA site & Around the Book Blogging Community
See more info and sign up for the event at the official Armchair BEA website.
I'm really looking forward for this event. You should participate as well!
