@esbe as someone who's subscribed to a lot of rss feeds: please don't put everything in the feed, it'll take ages to load and process each time
@electrickeet no idea, but the minimum depends on how often you post, you don't want someone to miss sth because they check manually. I'd err towards a higher number because computers are fast, it starts to become an issue on a webcomic with thousands of pages where I also have freshRSS extract the comic itself from the page
@electrickeet though even then the extraction would run post-deduplication so not that big a deal
