Honestly X is still pretty good for this if you follow the right people. The AI/ML research community is super active there - Andrej Karpathy, François Chollet, Yann LeCun, etc. Plus a lot of the good startups announce stuff there first.

For more traditional dev stuff, I've been getting good signal from newsletters like Changelog, TLDR, and Morning Brew's tech section. Not as real-time as the old blog days but decent curation.

Reddit's r/MachineLearning and r/programming can be hit or miss but sometimes catch things early. GitHub trending is also underrated for spotting new tools.
