Stack ExchangeAcademicEngagementKnowledge sharingQ&ASocial graphSoftware development The content of expressionengine.stackexchange.com (https://expressionengine.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 60,883 rows: 29,137 posts (12,477 questions, 16,369 answers, 140 tag wiki excerpts, 140 tag wikis, 8 posts of type 6 and 3 posts of type 7) and 31,746 comments, written between 15 November 2012 and 27 March 2024. Beside it are 9,276 user accounts, 49,788 votes, 19,218 badges awarded, 600 tags, 72,614 post revisions and 984 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 126 rows.
