OpenCollective says that the total donations are $1,107.75 USD with 6 contributors. I threw another 20 bucks at them after reading that, but it seems like at least ads or something would make sense purely from a financial perspective, since even with 8M impressions, not that many are interested in donating sadly.
I do really enjoy the site, it has lots of technologies listed and looks very pleasant. Actually used it just this week, since I started building an API with the previous .NET LTS version but a new one came out, so I suddenly started having to install older package versions for compatibility reasons hah.
What are the operational costs of running such a site?
We're looking to join OpenEoX.org to standardize EoL information publication, but that requires a lot more funds (https://github.com/endoflife-date/endoflife.date/discussions...).
We also have a pretty long roadmap (https://github.com/endoflife-date/endoflife.date/issues/2108) that focuses on integrating better with the sbom ecosystem (We want to make an API that does SBOM->EOL alerts for eg). Such projects require a lot of development effort, and we'd like to be able to sponsor it on our own (via grants/donations).
You could consider making more expensive features paid options? Definitely tradeoffs there but it is an option, especially for business-useful features
Do you have plans to monetize it? I hope not. Because this is a thing that should exist in the world. I would much rather support this via donations than ads or anything else.
