Within the first hour of threads going live, about a dozen of those im following on ig have joined (and began posting). When it’s fully federated, could this be the entry level platform the fediverse needs to push it into average use? I have a slight feeling it’ll be a BeReal type scenario where people use it for a few months and then move on, but id be stoked to be able to have my friends and family see my posts on mastodon/lemmy.
Threads will mainstream threads.
Any good content here will be available to the Threads users, who will be oblivious to where it is coming from.
Eventually, Meta will take steps to break compatability, and lots of the most prolific contributors from here will move to Threads exclusively (for a host of valid reasons).
When it is no longer in Meta interest to federate, they will stop.
The fediverse will continue, but it will be weakened by it’s temporary reliance on Threads (who could afford to host large images/videos/etc, have lower latency, etc etc).
