eBooks worked for me in 2014 & 15. I am the author of an ebook Trello Dojo (https://leanpub.com/trellodojo https://leanpub.com/trellodojo). I update it periodically and earn a couple hundred dollars a month. Lots of people from all over the world tell me it has helped them, which feels like I'm doing honest, good work with it. I'm not going to retire early from just that, but really want to do a few more, and possibly expand that concept into niche sites/training/etc. niche sites and blogging have not panned out for me (yet). I feel that's more a lack of time/effort on my part. A test effort showed me my niche could work, but I just haven't committed to really getting it rolling. I'm also a software developer and have a few service type sites up my sleeve. My thinking (as yet unproven in my own life) is that relatively simple subscription services that "do one thing well" and can be marketed to businesses and government agencies can earn well with minimal ongoing investment. The trick there would be to automate as much as possible- especially support- without sacrificing quality, and periodically dedicate resources to keeping the technology current (easier said than done, I know) It's hard to balance a current "non-passive" job, family, and side passive gigs, but it _can be done_.
