Stack ExchangeAcademicEngagementKnowledge sharingQ&ASocial graphSoftware development The content of substrate.stackexchange.com (https://substrate.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 19,756 rows: 10,401 posts (4,891 questions, 5,362 answers, 69 tag wiki excerpts, 69 tag wikis and 10 posts of type 6) and 9,355 comments, written between 8 February 2022 and 31 March 2024. Beside it are 4,225 user accounts, 27,630 votes, 8,413 badges awarded, 494 tags, 28,678 post revisions and 1,033 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 39 rows.
