If you haven't been paying attention, It has been only barely 3 days since #Pebble closed its doors and many are moving to the #Fediverse and settling in over at https://pebble.social.
However, prior to that, when the announcement of the shutdown was first made, the first thing that happened was the creation and marketing of the hashtag #T2pub. The purpose of the hashtag was to make it easier to discover content from former #PebbleIs users, regardless of where in the fediverse you are located.
A few days later, the @t2pub was born. It is a fediverse #group. Anyone who is following the group is guaranteed to receive the latest T2pub group content shared by other users. As compared to the hashtag, it relies heavily on if the user was already discovered by an account's local instance.
Finally, pebble.social was born; and former Pebble users who migrated earlier to the Fediverse are moving to it.
Now, this is interesting because there is now a growing sub-community within the Fediverse network. Former #T2social users who primarily wish to interact with fellow former #T2 users; while, at the same time, keeping the lines open for interaction with the wider fediverse.
If we look at it from a #SciFi or #Fantasy or #ScienceFantasy perspective, if different star systems (for example Sol System) are the software, and the different planets (for example Planet Mars) are the instances; we've just witnessed migrants from the “Pebble Universe” after it collapsed.
These migrants found a planet of their own and called is Pebble.Social which is located in the Mastodon star system.
And those who landed on other planets are relocating to the Pebble.social Planet; however, as they are still settling in this new world and new universe, they are still primarily concerned on their own planet. Building it up. Setting up their communities.
