I just converted www.jerrypournelle.com/chaosmanor
to a WordPress site with Atahualpa 3.6.7. (Jerry Pournelle: famous science fiction author, and Byte columnist from way back. Arguably has the first blog, since he's been doing that for decades.)
His Wordpress-based blog just went live last weekend. His daily page view count is around 8000.
He composes items in Word 2007/blog mode, then Publishes from there. (He's not quite ready to work with content in WP-editor mode.) We're still tweaking the design a bit; one major 'wish' is to have a 'weekly' view (Sunday through Saturday).
Site is at www.jerrypournelle.com/chaosmanor
Another site with average 2000-2500 views/day is www.thebbqgrail.com
A great place for anything related to BBQ. That one has been active for more than a year.
Have done many WP-Atuhualpa-based sites. Some with e-commerce.
Rick....*big* fan of Atahualpa.
