There were several actually. That's fairly normal for them, they tend to pop in and out of the forum. I wouldn't read more into it. Their developers are usually pretty honest and open about sharing information. I don't think they left just because of all the zoom/annotation questions. Hopefully it just means they're busy working on them.
