I can see how it can solve real problems, I just never hear it doing so. From my observation (correct me if I am mistaken), these projects add a lot of features continually, which is what devs are great at. But I don't see work or an investment being made in quality,reliability and performance. They desparately need central servers that use the metaverse behind the scenes but invest heavily on good UX. Is mastodon inherently better quality than fb? Is matrix more reliable than signal and whatsapp or better performing/moderated than discord? For most people , the decentralized and privacy sensitive features are merely the decoration on the icing of the cake.
