  • Silicon Valley doesn't understand the concept of fun
    Old-time TV used to have ads for alcohol, cigarettes. Late-night shows, sometimes risky in europe (i.e. tits) had ads, lots of them. Google + Facebook, like the puritanest of the puritan americans have made that a no-go. It's not clear who decided it first, but basically anything that the local church might frown upon has become unmonetizable and unadvertisable. Of course you won't have fun things when you do... - Source: Hacker News / 6 months ago
  • Hold the postmortem: The metaverse was never alive in the first place

  • R.I.P. AltspaceVR I will miss you
    I know a lot of you probably do not care that AltspaceVR is going away in March but I will miss it dearly. Sauce : https://altvr.com/ I was on the platform at the very beginning using an opendive 3D printed DIY headset my phone and trinus. I then made the switch to GearVR in 2017 and had great fun playing cards against humanity until they ended mobile support. I still visited occasionally the past few years on...
