Stack ExchangeAcademicEngagementKnowledge sharingQ&ASocial graphSoftware development The content of sqa.stackexchange.com (https://sqa.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 76,837 rows: 37,379 posts (11,681 questions, 24,818 answers, 436 tag wiki excerpts, 436 tag wikis, 2 posts of type 3 and 6 posts of type 6) and 39,458 comments, written between 3 May 2011 and 27 March 2024. Beside it are 50,127 user accounts, 114,399 votes, 62,859 badges awarded, 467 tags, 121,927 post revisions and 1,701 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 140 rows.
