X said communities were done so I stoped posting or replying there I loved posting there, but oh well. a few months later… they are still in my feed feels like I have been bamboozled the day I decide to post there again will probably be the day the remove them

not impressed with Fable 5 I will stick with composer 2.5 we are at a point that the benefit is so marginal using these frontier models yet the cost is astronomical

YC's position in Mercor would be worth >$1B today if they hadn't rejected us in 2023. They passed because a previous recruiting startup didn't work out. These days, YC seems more focused on funding clones of fast-growing companies than making contrarian bets. What's the largest company YC has invested in over the last 3 years? The hit rate seems surprisingly low.

Spare some feedback on this design? I have spent to much time looking at it So I'm not sure if it looks good or not
