Recently Google decided to change the way the API for Google Translate works and, more importantly, to change it from a free service to a paid service. On 12/1/2011, Kindlefish will no longer work unless I start paying Google to use their API. The fee isn't that much overall ($20 for 1 million characters), but I will need to rework the site to update it to the new API and I don't earn any money off of Kindlefish.
If you are a fan of Kindlefish or would like to support the website and service, please consider donating by using the link below! If I get enough donations ($40?) to keep Google happy and pay for the coffee needed to rework (and improve) the website, I'll keep it up and running. Using the new API, Kindlefish will end up being more reliable than ever and continue being there for you whenever you need it.
Update: So far, there haven't been any donations. I've been happy to provide Kindlefish as a free service so far because Google Translate has been free for me to use, but at the moment it looks like Kindlefish will go down temporarily in order to assess whether I want to start paying for access to the new API.
