 An older version of this blog was published on 30th April. Based on feedback from some early readers on the number of links for specific sites, we have updated the numbers. The Tattle blog, unlike our peer reviewed papers and reports, are intended as updates about work-in-progress. Blogging about intermediate results is a part of our ethos of working in the open. But, we realize that data analysis that is 'work-in-progress' is more open to misinterpretation than 'work-in-progress' software. Moving forward, we'll ensure that all data analysis that is published as work in progress has a note stating this at the top of the blog.
 
+**Here is what changed between the first version of the blog and this one:** 
+In the first version, when extracting domains from the community notes, we didn’t separate the fact checking specific path from the domain name. For instance the website domain could be the-true-guys.com and their factcheck articles could be on the path the-true-guys.com/factcheck-articles/
+In this current version, where it was easy to find the fact checking specific path, we have analyzed those. In the table, we have listed when the count refers only to fact-check reports and when it includes both fact-checks and news articles.
