The Wikipedia article on hash tags clued me in to micro-memes and had me looking up the word “concatenated.” My favorite concatenated micro-meme? #fridayreads. Every Friday, thousands of people post what they’re reading with the hash tag #fridayreads, becoming what CNBC recently called “the book club of the Twitterverse.”

#fridayreads is a fascinating snapshot of people who love to read and what they’re reading. Starting this week, there’s even a new FridayReads page for Facebook: www.facebook.com/pages/FridayReads/107931275939402.

Join in the #fridayreads fun and be part of a global community of book lovers. Prizes from books to chocolate are given to randomly selected participants each week — including a free subscription to Shelf Unbound indie book review magazine. What are YOU reading today? #fridayreads wants to know.
