Nope. When I left reddit, there was a lot of people pushing for discord like its a replacement. Its very much not the same thing. Its basically a chat room with a handful of extra features
And in a room with any measurable amount of people, it quickly becomes impossible to find anything or track conversations. I'm in a couple developer servers for some hosted apps, and goddamn is it painful when I actually need to use them for support. Hell, even my local friend group server with a dozen or so people can be annoying when it's really popping.
I use discord to contribute as a dev for open source project and constantly needing to pull up years old conversations for reference. One of the few ways my close-to-perfect memory actually helps out is remembering who said what and when word for word so I know exactly what keywords to type into the search bar. Its such a good feeling being able to go "oh yeah speaking of the suggestion on adding ambient tracks for X thing one of our composers already made test tracks for that like two years ago. Let me hunt down the tracks they uploaded. Now who exactly was that composer again? I think it was X, let me browse through their chat history pinpoints it on first try
Even if it wasnt, i fail to see how going to Discord serves any of the purposes of reddit. So from my understanding you really have to go out of your way to choose Discord as a replacement over Lemmy. That is if you know Lemmy exists.
I think the forums achieves this better. You could have the OP make a post on the forum, and then have emoji reactions be upvotes and downvotes. But it's not really meant for it, not the same.
I often have to use the search feature to find people in severs, and half the time they don't even show up. Then I go to @ them in a channel, and then they suddenly show up in the search again, it's ridiculous
