Pecha Kucha Night is "a place for young designers to meet, network, and show their work in public." But here's the catch: Each presenter is given just 20 seconds to show 20 images, making it lively and fun. 80 cities now have these events. Check out where here.

Check out Ethnologue for a comprehensive cataloguing of the world's known living languages -- almost seven thousand of them! From Senegal's 36 tongues to China's 235, the site breaks down languages by size, family and country. Fascinating fact from the site: "95% of languages are spoken by only 6% of the world's people." Wow.

Last week we brought you blog book tours. This week it's blog book reviews! Check out these websites for book reviews and commentary:

Curled Up With a Good Book

This week in our Blog Du Jour blog recommendations we talked about "virtual book tours." But what if you want to actually meet your favorite author, for real and in the flesh? Check out BookTour, "where authors and audiences meet," a listing of author events around the country.

No time to stop by the local bookstore to listen to a reading by your favorite author? Why, check out a "blog book tour" -- where writers visit blogs instead of stores. Here are literary blogs that feature authors, their books and book-related conversation, all at your computer-driven fingertips:

The Elegant Variation

Major Bedhead Reviews

Book of Kells

Writing in the Mountains

Debbie Shults, the veteran teacher, literacy coach -- and now blogger -- we interview in this week's "Teachers at Work" column, recommends these blogs written by and for teachers:

"Jess Timmons, my young blogging mentor, has a blog called Meaningful Fragments. Jess's website was my original inspiration, and reading her posts keeps me in touch with what our best young teachers are thinking."

"Zach Chase, another young teacher in the Sarasota County Public School system, has a fabulous blog called, Mr. Chase's Room. He is a definite guru in the world of educational blogs. His posts are always thought provoking and innovative."

"Darren Kuropatwa. I found his blog, A Difference, through a link on Zach Chase's blog. Darren is a math teacher who writes about all kinds of ideas, especially what's on the cutting edge in integrating technology into the classroom."
