The old blog was just pages in the same CMS as the main website which wasn't really tailored to blogging. So we're separating those two: www.tempoplugin.com for the e-commerce part of Tempo and blog.tempoplugin.com for the blog. We also have support and documentation sections over at feedback.tempoplugin.com and wiki.tempoplugin.com
The blog is now running on WordPress (the most popular CMS in the world), hosted by WP Engine (they also host the blog for Atlassian, Foursquare and other smart companies) and uses a CDN to make sure it loads up fast.
If you have any feedback please let us know by adding a comment. Do you like the changes? Do you have any suggestions? You can also contact the Tempo team here.
