The best thing about kirby is that it can be used by all types of users in terms of experience and knowledge, whether they are newbies or experts! It takes some time to get used to its interface but once you're there, you'll love it and use it every day. I'm currently using Kirby for creating eBooks with my clients, and we've been very happy so far. Not much at this moment. But overall i think everything's fine as long as your team knows how to work with such software; if not, then maybe hire someone who does know what they're doing before spending too much time/money on their services (and I don't mean hiring only an editor). We needed something for our digital products which was easy enough to edit content without any coding or technical skills required.
