first, i just want to say that i never thought about the term "decentra-web" for these web revival spaces, and i have to say, that's a pretty great term!
to answer the question, yes. very much so. the customization is a big part; by taking one look at me, my website, or my work, it's clear that i was told to "be myself" one too many times, so i naturally take self-expression very seriously. but also, the indie web spaces are less confrontational and full of "stuff". that's one of my biggest gripes with big social media; everyone is so confrontational, argumentative, always looking to pick fights over things that don't matter, and they buy stuff they don't need just to be "cool" before throwing it away. twitter, reddit and tik tok are especially bad with this. you know that one twitter meme that goes "'i like pancakes' 'so you hate waffles?'" yeah, big social media is basically that plus conspicuous consumption. it's rage-bait. on the decentra-web, i don't have to worry about that
the hardest part is convincing others on big social media to get into the decentra-web. i know it's hard to move off of something you've used for years. but i'm sure many of them are wishing for an internet space where they can truly express themselves without worrying about algorithms and being advertised to all the time. so why not start now?
