Stack Exchange — cstheory.stackexchange.com
The content of cstheory.stackexchange.com (https://cstheory.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 101,887 rows: 30,077 posts (12,858 questions, 16,869 answers, 164 tag wiki excerpts, 164 tag wikis, 2 posts of type 3, 15 posts of type 6 and 5 posts of type 7) and 71,810 comments, written between 16 August 2010 and 31 March 2024. Beside it are 50,286 user accounts, 280,775 votes, 77,211 badges awarded, 506 tags, 106,750 post revisions and 2,824 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 560 rows.
