What was the update? If it's casual fare, you can probably make a quick pass at a joke ("Around") or just outline something notable that's happened since the two of you stopped communicating regularly ("Got a job working as a...").
If it's something more serious, though, you may want to send a PM and ask him/her exactly what s/he means. But that's only if you were particularly close - otherwise, you can probably blow it off by utilizing the second option I've mentioned above.
The update was just a short rant about something. I think replying with "Around" would sound incredibly rude. We weren't close, just kinda friendly, or maybe friends, idk.
