Wikipedia sums it up nicely:
"A blog carnival is a type of blog event. It is similar to a magazine, in that it is dedicated to a particular topic, and is published on a regular schedule, often weekly or monthly. Each edition of a blog carnival is in the form of a blog article that contains permalinks links to other blog articles on the particular topic.You can see a list of over 2000 carnivals on the Blog Carnival page.
There are many variations, but typically, someone who wants to organize a carnival posts details of the theme or topic to their blog, and asks readers to submit relevant articles for inclusion in an upcoming edition. The host then collects links to these submissions, edits and annotates them (often in very creative ways), and publishes the resulting round-up to his or her blog.
Many carnivals have a home page or principal organizer, who lines up guest bloggers to host each edition. This means that the carnival travels, appearing on a different blog each time."
The Giving Carnival was started by Sean Stannard-Stockton of Tactical Philanthropy. This month it was hosted by Gayle Roberts of Fundraising for Nonprofits. The theme was "Fundraising for Nonprofits" and had 22 contributors (including me).
The Carnival of Nonprofit Consultants was started by Kivi Leroux Miller of Nonprofit Communications. This week the Carnival was hosted by Nancy Schwartz of Getting Attention and the theme was, "How to Use Online Video to Strengthen Your Nonprofit Marketing Impact." Jeff Brooks at Donor Power Blog is the host for next week's Carnival. He will give bonus points to posts that argue one of these two positions:
--What's good about fundraising
--What's bad about fundraising
