I would maybe prefer something that is linux inspired, but https://www.phoronix.com/ is too wordy for me. Something like https://www.planetizen.com/ is cool for me, but maybe too specific.

Suprisingly, Reddit is cool if you choose your subreddits wisely. But apart from that, tbh I think it's probably better to read actual books on topics you find stimulating or maybe something like the Economist.
