@tomaldertweets Shrinkflation

can someone explain why?

Just found out my newsletter was featured by @readwise!

@UltraLinx @dannypostma Any thoughts on the Xbox Ally X? Would be cool to see you cover it on release.

@dannypostma Exactly why I have mine. Being able to play my Steamdeck for a whole flight is a time killer.

~5 hours of extra play time with this Anker. Not bad 👏

You are what you do when no one is looking.

@EricJorgenson @pnickdurham Usually agree with you Eric, but this is just plain wrong in my experience. A single post brought me more than 700 new subscribers. Another brought me nearly 400. Discoverability and engagement are far better for me over there than on any other platform.

@oldbooksguy I'm an atheist, btw. x.com/G_S_Bhogal/sta…

this meme is retarded. it's used by atheists to push their cheap nihilism as if it was some profound truth. "muh universe big" doesn't imply that human life is meaningless. if anything, it implies that the scope of human activity is infinite, and thereby man is uniquely blessed

I'm partnering with Derek Sivers to give away free physical copies of his latest book to my readers. Read my latest post in the replies below to find out how to claim yours. There's no limit to this offer, so share it far and wide.

@thinkobelisk Agreed. There are many important ideas from Japan alone. I’ll be sharing more soon.

@mntlmodels Eastern philosophy has a lot to teach us. Finding profound wisdom in details we gloss over is seriously underrated.
