Stack Exchange — or.stackexchange.com
The content of or.stackexchange.com (https://or.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 28,904 rows: 9,983 posts (4,082 questions, 5,547 answers, 172 tag wiki excerpts, 172 tag wikis and 10 posts of type 6) and 18,921 comments, written between 30 May 2019 and 31 March 2024. Beside it are 10,212 user accounts, 54,874 votes, 16,705 badges awarded, 271 tags, 33,592 post revisions and 885 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 100 rows.
