What it does

That always felt sketchy so I built something different. you download your own file, upload it here, and everything runs in your browser. I NEVER SEE YOUR DATA, NOT EVEN FOR A SECOND. Built the whole thing as a single HTML file with vibe coding This is the first product i have ever build so an honest feedback would be genuinely valuable.

So I just did my semi-annual "log in to Twitter to see if it's any good yet", and found that in my absence I had followed a few thousand new spam accounts. Sweet. That explains why they emailed me and forced me to change my password last year. Being Awesome, Twitter doesn't have any way to simply toss out all your followers and start from scratch. And none of the spammy apps claiming to do so actually will (even seemingly after charging you money to try). So instead, I just pulled open the Dev console and did this:…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
