I guess this has been happening for a couple of days now (maybe more?), but the API was slightly changed and functions like “posts/recent” are not returning what they should. The “extended” field of the responses just mimics the “description” field now.
This is why the listing of links in my homepage is kind of weird with the description exactly equal to the title. Still, it does show that they are working on the API which can only mean good things are coming! (We hope…) ;-)
[Update:] Things are really moving in there. The API is acting as it should again.
