I have worked on a lot of products over the years, a LOT, probably enough to compete with Google Graveyard. However, none of them have really been successful. I find myself following the same doomed failure for every project, build it, post it, let it die.
By that I mean I get right down to writing code day one. I'll do a little but of validation by seeing if there are competitors, seeing if I can do better, a little keyword research, but then it's headfirst into my favorite IDE.
One the product is finished I'll post it around on different sites, Reddit, Indiehackers, ShowHN, Insta, Twitter, etc. Throughout development I may post about my idea once or twice just to get some thoughts, but typically I build in "stealth mode", because most of my ideas aren't groundbreaking they could be easily replicated if someone wanted. This rarely leads to a ton of engagement, more likely it will return no interest. This is where I'm at with my latest released product ImgMark.
After I build it, and post it around, and get no engagement, I find myself losing interest and letting it die. I'll typically move on to the next project and just let the site run until the domain name expires and I don't renew.
I now want to try really hard to break this mold, whether it be saving my latest product or doing my next project right from the start. I know I need to start earlier with spreading the word, I know once I build it people won't just come, but it seems like at every step its just simpler to push through to the next one without doing that one right.
