I'm ignoring bluesky, it doesn't seem to bring anything new to the table. For me, #Nostr is the only platform I use. We use Twitter / X at work, primarily because our clients are there, but for me personally, I'm pretty comfortable on Nostr and will no longer post to Facebook or X.
Now I post on Yet Another Social Network:

Because, hey, we've now got choices eh? 😘

Still on the fence as to how valuable Bsky.app will prove to be as a social space. Not much enthralled about Twitter/X, and indeed I believe the future of social media is on decentralized (Nostr) and federated (e.g. Mastodon) networks.
