EDIT: This is fixed now. I'll leave it here for people who want to see how it was done.
I was playing with the Glitch API, and I noticed in the /simple/players.fullInfo , it gave the last location of a user. But, that isn't all. (warning: geek alert) It gives the TSID of the last location also, so you could use that to get to the location page. With this, I managed to find a new day to dev stalk! (I'm sure the devs are soooo happy now :D) Let's start
1. Find a dev you want to stalk (I'm going to use Lisa. Sorry Lisa!)
2. In the URL bar, there is their TSID. (the letters and numbers after profile/) In this case, Lisa's is PCR11BHHPVN1AIQ. Copy that.
3. Next, head to the API explorer (http://api.glitch.com/explore/), and choose /simple/players.fullInfo .
4. In the Arguments box, put player_tsid=their_tsid.
5. Press the Test button, and you're going to get a LOT of stuff. Look for location.
6. There is a TSID for the location. Copy that.
7. Go to http://beta.glitch.com/locations/the_location_tsid/, where the_location_tsid is that TSID you just copied.
8. ???
9. PROFIT! (and spoilers)
If you need to know whether or not a dev is in a cool place, just look on your friend's list. ;)
P.S. Tiny Speck, if you reaaaalllyyy don't like this, I can take it down. I did this simply to show others what you can do with the API ;)
P.P.S. If any devs want to make a web app for this, go ahead. Glitch Dev-Stalker, anyone?
edit: I realized I forgot the API calls the first time. I am so very silly. They're there now. oopsies.
