It’s another type of content aggregator like Lemmy and Mbin. Totally unique software, not just an app.
It’s not as well known because it only started development a little over a year ago, well after the APIcalypse when most of the Lemmy userbase came over from reddit. But it’s been improving rapidly and already has a lot of innovative features that Lemmy lacks. I believe that one of those features is better compatibility with Mastodon, but I’m not entirely sure. It’s also written in Python which makes it easy for a variety of developers to contribute if they so wish.
Indeed.
Although the private voting feature isn’t all that effective. First of all it doesn’t work with trusted instances (which includes many of the big ones), and secondly it only obscures the voter identity, it doesn’t completely randomize it.
See these posts for context.

I don’t necessarily think these limitations are a bad thing, because totally private voting could theoretically be a vector for bad actors to manipulate the visibility of content on the fediverse. This solution provides some protection for the average user but also makes it possible for admins to identify vote manipulation if it becomes a problem.
