The Britblog roundup is a weekly summary of the best of the British blogosphere, selected from nominations submitted by bloggers. Post included may be either by British bloggers, or from people living in Britain. There are around 10 rotating hosts, listed on the weekly carnival's home page.
The Britblog roundup originated by Tim Worstall on February 20, 2005, and it went on the road around the current hosts in 2007. Some roundups include extensive commentary on the posts submitted; others are more of a listing.
