I'm not particularly invested in Bluesky, but I found it to be the polar opposite of Twitter. It's like everyone who quit the twitter band wagon just went to the twitter clone, as a middle finger move. It's a ying and yang.
I'm still on Twitter, because some people just haven't moved on and I still find their content valid. I vomit a little if I happen to click the sidebar and I want to close my account nearly every visit. I honestly hang by a thread just because some accounts there don't offer an alternative (and Musk removed reading content unauthenticated).
I'm not particularly invested in Mastodon, but I must say that it is where I found the best value per minute. It feels like the natural follow up to Google+. I find it the most 'balanced' between Bluesky and Twitter.
