For hacker news and Twitter. The agents being hooked up are basically click bait generators, posting whatever content will get engagement from humans. It's for a couple screenshots and then people forget about it. No one actually wants to spend their time reading AI slop comments that all sound the same.
My bad. I was asking who thinks that it is good value (for them) to use their token budget on doing this. I truly don't understand what human thinks this will bring them value.
The "value" is seeing their AI agent come up with something compelling to post based on the instructions, data and history that's been co-determined by the human user. It automates the boring part of posting to HN/reddit for karma points in a way that doesn't break the typical no-spambot policies in these sites.
