Communications of the ACM


About The Blogs

The Communications site publishes two types of blogs. The BLOG@CACM expert blog resides on-site, and the Blogroll of syndicated blogs reside off-site. Both blogs rely on a continually evolving community of bloggers. If you would like to recommend a blogger or volunteer yourself for BLOG@CACM, please contact us at

Our bloggers discuss relevant computing topics and encourage comments about their posts.
