    A few days ago, I responded to a comment by bloggergirl offering to read anyone's web copy and help. I shot off an email hoping for a paragraph or two of feedback on my startup's copy. Instead I received a professional, detailed deck of tons of invaluable well thought out feedback. It must have taken her an entire afternoon. Here's a link to it: http://www.slideshare.net/shereefb/recommendations-for-bettermeans To top it off, this isn't someone with a lot of free time on her hands, she's only days away from launching her own startup (page99test) This community blows my mind!

    Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas

    Every batch, many founders get rejected due to basic application mistakes, missing key criteria that YC partners explicitly look for. We learned this the hard way, which is why we built YC Score. Simply upload your draft PDF or fill out our YC-mirrored form. Our AI analyzes your responses against 25 critical factors that can make or break your application, from technical credentials to market validation. For instance, when YC partner Dalton Caldwell notes that teams with technical founders have "5x better odds," you need to know before submitting. YC Score flags these deal-breakers and shows…
