I believe Renai was writing fairly regularly then joined the Greens in some position and Delimiter went on hiatus. He finished his position with The Greens and started writing fairly regularly for Delimiter joining the Parliamentary press core (or whatever you call it).
He's now shifting from an ad based site to charging a subscription like Crikey (with some free articles mixed in). Not too sure if this model with work but I've always found the articles quite good.
Why do I know all of this?
