We are reviving the blog! We also moved the prior posts (2013 and before) that lived on Wordpress to this new home on openintro.org. We plan to use the blog for announcements, share plans, and discuss different resources online (OpenIntro and otherwise). Posts will be at a cadence of about 10 per year.
Additional blog functionality is also coming, including commenting. In the meantime, feel free to start discussions in the Forums, and if there are topics you'd particularly like to hear about, send us a note.
