I like the fact it is simple and truly works. You will on occasion be congratulated on the many times you've used it with a request for a donation. This is not a bad thing because it costs to create and continue updating something like this. Since there is no corporate sponsor it's up to US to keep it in existence by making a donation sometimes. No donations or not enough donations can mean the demise of something we use and find useful. So, pay them something so it stays around, please.
