How about if someone offered to take over the project(s) from you? In effect equivalent to the above, but non-fungible.
But thank you for asking.
I do not know what the answer is but at the moment I see no reason to be idealistically trying to preserve the information for the benefit of other people and I find it incredibly offensive that people are suggesting I should given that I am homeless. Either give me money, help me effectively monetize it, or say goodbye to it. If it has value, it should be worth something to people. If it is not worth something to people, then bleeding a homeless person for sympathy seems pretty freaking sick.
It sounds like you are not making money, so either A) fix something so it makes money or B) toss it.
Just because something is useful does not mean it is profitable. As with all things in business, you have to find someone that values your service enough to pay for it (in some capacity).
I wanted to write software for academic biologists because I'm an ex-biologist...but they don't want to pay for it. Doesn't matter how useful it is if no one is willing to pay.
So, shut it down. Kill it with fire and move on.
At the moment, $1700 in donations (edit: and a few links/promos generating traffic) would convince me to keep it up for another year. That would not get me off the street but it would pay my taxes, pay the webhosting and domain name and help me and my kids eat properly for the next two weeks. In other words, it would alleviate some serious immediate stressors. But no one will blog about it and announce it to the world and tell people to support it or open their own wallet up. So I think I will try the e-book idea and then move on to other projects with an eye towards making money first and foremost.
If someone out there thinks your information is valuable, they can pay $15-25 bucks for it; at least then you don't have to keep paying/updating your site and you might put a few bucks in your pocket.
