The last couple updates made it easier to access the trending feed (which afaik has existed since 2021) and added features like quote posts. Bluesky starter packs and custom shareable feeds are definitely its major perks.

The odds though bluesky will get bought up by right wing billionaires in the next 10 years is almost 100% unless there's a major change in media management laws so don't get too attached to bluesky since there is like a nonzero chance trump jr buys it with his crypto bribes.
