Not Vegan, But: Probably needs a rest day in between workout days, adequate sleep or a calorie surplus. If he’s up for it, he should get his nutrient levels checked. There’s also this problem where people on the internet set unrealistic expectations of how fast your gains should be.
The ones most important to me are:
tagging features, tagging hotmaps for communities, search by tag, comments from crossposts is combined to the viewer (there’s a divider to show which community),
when someone posts from a certain instance like beehaw you get a reminder about their community standards, user flairs
less resources needed to load stuff (great for third-worlders like me), post and comment subscriptions, feeds (something similar to a multireddit)
topic categories (do note that topic ≠ community) like Regional > Asia > Philippines in which each topic category shows all posts made by communities in the category. For example if you are in Topic: Regional you get posts from all regional communities, in Topic: Asia you get posts from all communities based on Asia.
