Life happens and things change. Starline has been putting Candi online, apparently, since June 25 2004 - not much shy of TWELVE YEARS ago.
In twelve years, priorities can shift. A lot. I've read several webcomics that ran a lot less than twelve years and them just stopped updating with no notice or explanation. Some did worse than that. One of the best got rebooted into something much more boring, and then stopped updating a couple months later, and then the original (good) comic was removed from the website in order to not draw attention away from the boring one that wasn't being updated either. Another had a good story going and then the author posted a couple pages that were just walls of text bringing the story to something that technically constituted a close... not a good close in any sense and some of the characters were barely recognizable, but a close... and stopped.
Candi's still running.
