Stack Exchange — coffee.stackexchange.com

The content of coffee.stackexchange.com (https://coffee.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 9,510 rows: 4,525 posts (1,475 questions, 2,898 answers, 71 tag wiki excerpts, 71 tag wikis, 9 posts of type 6 and 1 post of type 7) and 4,985 comments, written between 27 January 2015 and 30 March 2024. Beside it are 11,594 user accounts, 22,128 votes, 14,615 badges awarded, 114 tags, 11,825 post revisions and 622 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 18 rows.
