🆕 blog! “Rebuilding FourSquare for ActivityPub using OpenStreetMap”
I used to like the original FourSquare. The "mayor" stuff was a bit silly, and my friends never left that many reviews, but I loved being able to signal to my friends "I am at this cool museum" or "We're at this pub if you want to meet" or "Spendi…

Next steps:
* Record who is following it.
* Post to all followers (not just me).
* Stable URl for posts.
* Front end for picking locations nearby.
* About a dozen other things!

in reply to Terence Eden • • •Nice! My toy server can now:
✅ Record who is following it.
✅ Post to multiple inboxes.
✅ Generate a permalink for its posts.
It doesn't do:
❌ Signature verification
❌ Handling replies, likes, or unfollows (it is a read-only account)
❌ Showing number of followers, posts, etc.
Pretty happy with that.
Next step - a UI so I can actually send custom posts.

Next stage is making a button to send that location to my ActivityPub server to send out a message.
(This is crappy code, poorly architected. Just a Proof of Concept.)

in reply to Terence Eden • • •I've just reposted a public status from my new location check-in service.
It doesn't handle replies or likes, but you can follow it.
Expect buggy and untested weirdness 🙂

in reply to Terence Eden • • •It's all working!
You can follow @edent_location for my "FourSquare-style" check-ins to locations.
TODO:
📸 Upload and store photos.
🔣 Set the language text to prevent spurious "Translate" options.
🖼 Make the interface look nice.
🔒 Better security
👨💻 Tidy up the source code.

in reply to Terence Eden • • •Image upload works! And those photos percolate through the #fediverse!
I still need to add proper alt text (just a static description for now).
And the UI is 💩
But I'm pretty pleased with how far I've got in a few hours of hacking away.
It is *totally* possible to build a location-based service on top of #OSM and #ActivityPub!

in reply to Terence Eden • • •Goodness me! The ActivityPub network is chatty.
In the last 6 hours, I've received 371 different messages to my single-user inbox.
Most of which seem to be from servers announcing users have been deleted. They're not users or servers I've seen before.
Is this normal?
