One of the best things about reddit was looking for answers or other users with the same problem as you, and since Google didn’t really help with that anymore and instead insisted on giving you business results, the best practice was to put your search terms in followed by ‘reddit’ and you’d find your answer.
Why are people using a site named after the place they purposefully left with just one letter changed?
Presumably because reddit itself has a lot of positivity and memories attached to it for a lot of people - it wasn’t the site that people wanted to leave, but rather the ceo and staff behind it.
Because the f stands for federated and it’s the biggest German node?
Feddit is the name of a Lemmy/kbin style federated instance.
