Openvibe, previously Plebstr, previously Tweetoshi was a repeated attempt at creating a product for the wrong audience. It never served its purpose, even if the concept was novel at the time. Tweetoshi was a great idea for its time. They had zaps on Twitter before Nostr existed. Then they focused entirely on building a Nostr client, but it was so full of bugs that it was unusable. When Bluesky launched they pivoted to try to build a Swiss Army knife of decentral-ish protocols, but there was no appeal for it because social network users are tribal and bridging has never succeeded, not once that I can remember, and I have seen it tried for at least 15 years.
