I'm on my third. It's definitely worth it, but it's also, if done well, a long, hard haul. I think it's probably good to go into the project with an idea of why you're doing this. Are you creating what's basically an extended business card? Are you trying to help a particular kind of person that you know very well? Or are you chasing the goal of matching up a slice of knowledge with an eager audience? There are other goals. For instance, a lot of disparate experiences in your career can come together to help on a certain section you're working on. This allows you to personally gain some synthesis from your experiences you might not otherwise. You can find new depth in ancillary areas as you go through and footnote, adding more depth to the things you're talking about both for yourself and the reader. It's good to have those goals, even if you end up delivering a different kind of book than you had planned, because as a sole author something's got to keep you motivated for years. This isn't a software project, a job, or even a romantic commitment. Whatever you write, if it's worth writing, becomes a part of you. Like one of the other commenters says, if you have people on your team with published books they're likely to be busy responding to and helping folks interested in those areas. That doesn't go away simply because you move on. Probably the best advice I can give for new authors is that it should be a lot of work, and once you finish each phase you'll say to yourself, "Now comes the hard part". This essay writer gave 50 presentations. Wow! That number of public appearances alone is a non-trivial amount of work. Don't forget contacting bloggers, podcasts, tech publishers, and so on. No matter where you are in the process, next up is the hard part. None of that is any reason not to do it, of course. You just should be aware that if you're going to do a good job it's a major commitment. Prepare your outlook accordingly.
