It seems that the rss feed doesn't contains the post names anymore, and is missing content from the forums and wikis in comparaison to https://handmade.network/feed.
Thanks for fixing the titles. The rss feed doesn't contains wiki entries present on the site feed page. Is it intended ? Is there another feed for the wiki ?
I think there is a problem with the id system for wiki articles in the rss feed. After seeing that some articles didn't make it in my rss reader, I opened the feed file and saw that the articles were all there. But their id is always "none". So I guess that my reader sees the same id and reject the new entries if there is still an entry I didn't delete.
