I think ignoring is the wrong way to go for sure. Personally I un-installed my app for Lemmy but I might reinstall it.
The reason I might reinstall it is just to help improve Lemmy. For example, most of my news for League of Legends came from the subreddit and the Lemmy community I found is basically dead. So, if I want to help improve Lemmy I could look at reddit for the news and then repost it (linking the original source, not reddit).
Also, think about all the subreddits that make content from Twitter and Tumblr, it's possible some people will want to be on Reddit and Lemmy for the same reason.
Yea I think there’s a healthy perspective here. Many want Twitter and Reddit to die completely. Realistically, that won’t happen, not soon anyway. What’s happening now is more of a fracturing where different people can be happy in different places in the same way that there was a time when everyone was either on Twitter or Facebook and that time passed too.
At the moment, they're a bit on the "too big to fail" side. Digg is still around, despite much of the user base leaving for Reddit, and I imagine both Twitter and Reddit will still be around in some shape or form, even if Lemmy/Mastodon somehow make it big in the same way.
That's not even getting into things like how Reddit posts are still some of the more useful sources of information/discussion on the internet, due to the decline of forums and bulletin boards, so people will end up returning to it in some shape or form, if only to try and get recommendations/solve problems that they're having.
What might make them more likely to die is if they're not profitable, and they run out of money without being bought up, but that's less everyone leaving, and more the service shutting up shop overnight.
Which both parties seem to be trying to do in one way or another. Twitter is haemorrhaging money, and Reddit's recent controversies can't be doing good things to its stock price if the CEO more or less implied the company was not competent enough to make their own app profitable.
Exactly this. Lemmy is a little dead without content for us to comment on. I see no problem with reddit lurkers finding information and posting the original website's link. Like you said, social media is awash with reposts from other social media sites. I often joke with what new meme my wife may have found on FB that I saw it on reddit first.
There does seem to be one if you search across all Lemmy communities, but it is dead and very tiny.
Some of the users might also have retreated to the discord server, since /r/CuratedTumblr had an official one, while others just went for tumblr directly.
