I don't know anything about the mobile apps for the fediverse, but you can definitely search for communities from the Lemmy web UI (same goes if you're on kbin). If you go to the Communities tab there should be a search field in the upper-right.
Both the Lemmy and kBin UI show the domain of the link in a post. I would assume if someone got a post to the top of hot/active/whatever and edited the URL, then the UI would be updated to show the new URL's domain.
It'll have to be tested, but I'm not sure Perspectives will do what the 'reddit' query does for many people. I can only speak for myself, but I typically would add 'reddit' to searches because I was looking for thorough information on a subject, and I was certain there would be some random subreddit out there full of experts and enthusiasts on that specific niche topic. I don't want social media or influencer content, I want content from people with extremely deep knowledge about very specific things.
This article kind of misses the forest for the trees. While I agree with many of the author's points, that's not why the #TwitterMigration failed. It failed because Twitter/Mastodon isn't really a social networking site, and Mastodon didn't provide the same service that Twitter does. At its core, Twitter is about small numbers of (usually famous or important) users communicating with large audiences of followers. #TwitterMigration failed because not enough of those famous and important people moved from Twitter to Mastodon, so the average user had no content they cared to read. Seeing posts from your friends about what they had for dinner last night is all well and good, but the stuff people actually want to see is famous person A throwing shade at famous person B while famous person C talks about the new movie they're in and important organization D posts a warning about severe weather in the area. You don't go to Twitter to have discussions, you go to Twitter to get news and gossip direct from the source.
In contrast, sites like Reddit and kBin/Lemmy are about having group conversations around a topic. Interacting with famous people is neat but not the point. Think of Reddit/kBin/Lemmy as random conversations at a party whereas Twitter/Mastodon is some random person on the corner shouting to a crowd from a soapbox. #RedditMigration has a much better chance of succeeding simply because the purpose of the site is different. As long as enough people move to kBin/Lemmy to have meaningful conversations (aka content), it will have succeeded.
I think it's because there was a hope for wholesale migration of most/all users from Twitter to the Fediverse. Or at the very least for enough migration to make Twitter a barren landscape that would precipitate its imminent demise. Neither of those happened. Of course, neither of those are realistic outcomes either.
Yeah that could be worded better. No units. Resumably it's about the number of visits.
Looks like that number lines up with their reported DAU (daily active users) metric rather than site visits.
52 million DAU is about where Reddit was in the summer of 2021, per data on Statista. It also tends to vary up or down by a few million at each sample point, so we'd really have to see a long-term trend-line rather than a 2-week data snapshot to know whether the blackout had any real effect.
