I’m planning to publicly open up some of the @atexplore.social endpoints early next year. These endpoints are currently being used by the MCP server and webapp. I’m working on creating some documentation for these endpoints.

I mentioned a few days ago how my site content is now mostly stored in my PDS. I wrote a leaflet going a little more into detail on my setup.

I created a new landing page for the <a href="https://bsky.app/profile/did:plc:4fupyr7ei4zh7fb6hme7vko4" class="hover:underline text-blue-600 dark:text-sky-400 no-card-link" target="_blank" rel="noopener" data-link="bsky-mention">@atexplore.social MCP. I’m going to add better docs, but it’s in beta if anyone wants to try it.

I feel like “wrapped” features are a little overdone. Like everyone has one now, and most of them I could care less about.

There’s always so much nostalgia in these episodes. One of my favorites to listen to.
AIM should have lasted forever | Version History
AOL Instant Messenger was, for years, one of the very best things on the internet. Before iMessage and WhatsApp, before Twitter and Facebook, AIM was simply how people talked to each other online. Maybe it was how you casually chatted up your crush; maybe it was how you and your banking coworkers got deals done. On this episode of Version History, David Pierce, Victoria Song, and author and journalist Kyle Chayka tell the story of the best messaging app ever — how it was created despite the wishes of AOL executives, how it took over the web, and why it didn’t last. #AIM #VersionHistory #Podcast

i should say “sing in with your AT handle” is easily my second favorite.
sounds exactly like @ handle, but clear tie to AT and visually different
doesn’t require so much arguing, capitalizes on AT wordplay
but it needs to link to normie explainer etc

I’m pretty close to having all the content on my site pulling from my PDS. Earlier this week, I switched out blogs for Leaflet. I just made some changes to pull the about section from my PDS.

I’ve migrated my blog over to @leaflet.pub and plan on shutting down my Ghost instance later this week. I just switched out the blog list on my site this evening.

I had to clean this up a bit, but it’s working much better. Thinking about bringing this into @atexplore.social and creating some authenticated functionality.
I got Google Antigravity to setup AT Protocol OAuth tonight!
