Stack Exchange — hsm.stackexchange.com
The content of hsm.stackexchange.com (https://hsm.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 32,987 rows: 10,633 posts (4,576 questions, 5,805 answers, 126 tag wiki excerpts and 126 tag wikis) and 22,354 comments, written between 28 October 2014 and 31 March 2024. Beside it are 16,070 user accounts, 67,004 votes, 24,433 badges awarded, 273 tags, 38,531 post revisions and 1,228 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 98 rows.
