My position differs currently for Mastodon and Lemmy.

In the case of Lemmy, I’m not yet 100% sure. Lemmy’s strength may also prove to be a weakness I feel in terms of it replacing Reddit, in that the decentralised nature naturally creates a dispersion of the audience. While anyone on Reddit could create a community, having them in one place really funnelled people into logically named communities. On the other hand while subscribing to a number of communities for Lemmy, it’s not that infrequent to come across the same or similar community on multiple instances and then needing to work out where you want to go. On one hand it’s probably good to have the varying perspectives and culture this will bring, but I think it’ll also make it hard for users looking for that definitive place to go. It’s very much early days though and perhaps many of those communities will naturally assemble in mass on various instances once the dust settles.

We’ll see how that plays out I guess, and right now my Reddit use is at maybe 10-20% what it was and I’m really looking to invest my time here. I think with time that both Lemmy updates an 3rd party clients will make working across instances more transparent and in turn broaden appeal.

I’m more bullish for Mastodon in the short term. The reason for that is my usage concerns me looking to follow an individual rather than locate a community of individuals. Since people will have one account, there’s less impact caused by decentralisation as my interactions with a person I follow is very much 1:1 (unless for some reason they chose to create and maintain multiple accounts). If I want to follow Apple’s account, they’ll presumably have a single one versus there maybe being 6 viable Apple communities across Lemmy instances. I find my use of Mastodon in terms of user experience is much closer and familiar to Twitter than currently Lemmy is to Reddit. Additionally, once it’s enabled for ActivityPub, I think Meta having Threads throws significant support around that particular ecosystem, and brings it to the masses. Can’t imagine we’ll see a billion dollar company spin up a Reddit alternative that is Activity Pub integrated to give Lemmy that same boost, unfortunately.

To be clear I’m very supportive of both Lemmy and Mastodon and want both to succeed. I do think reddit being centralised has some benefits but, especially for people not looking to invest heavily in browsing across instances, and that it’s to be seen how Lemmy will evolve as it grows and if casual users will be able to sign up and easily find the communities and information they are after. The 1:1 person interaction for Mastodon I think simplifies things and Thread potentially will result in a massive boost for Mastodon. It’s early days for Lemmy and I can’t imagine in Jan or Feb that the majority of us here had even heard of it, let alone considered leaving Reddit. It’ll only continue to grow and I’m excited to watch it do so.
