And yes, disclosing the use of AI should be par for the course.
I've tried asking ChatGPT to recommend projects based on my interests, but ChatGPT heavily hallucinated or projected my interests onto irrelevant projects (for example, a project might be about developing a new programming language and chatgpt was like, "you could use this in your soap making hobby!").
The Who's Hiring posts have community sponsored indexers and its easy for me to query job titles relevant to me, but keyword search is not as useful here.
Lobsters had a weekly thread by caius called, "What are you doing this week?" People would post personal projects or experiences in it. On top of interesting tech, that let us pray more specifically for and encourage some in need.
The weekly threads might work here.
Also requiring disclosure of the use of AI in repos and especially (or perhaps specifically discouraging its use) when responding with comments to HN feedback.
I'll take this opportunity to strongly encourage sharing prompts (the newest tier of software source code) as the logical progression of OSS adding additional value to Show HN.
