Attribution and limitations on use?

[tucson-tom]

SimpleWeather appears to use the Yahoo weather API behind the scenes. Yahoo requires websites to display attribution to use their weather API. From https://developer.yahoo.com/weather/ :

Attribution Guidelines

Please follow our Attribution Guidelines for Yahoo APIs wherever you use Weather data from Yahoo.

I don't see the required "Powered by Yahoo!" logo or the required link in any of the demos. Looks a TOS violation to me.

Regardless, Yahoo appears to limit usage to personal use only (and non-profit orgs) for the free version of their API:

Terms of Use

The above feeds are provided free of charge for use by individuals and non-profit organizations for personal, non-commercial uses.

That sentence severely limits the usefulness of the Yahoo Weather API. I think you should mention this on your site to anyone looking to acquire weather data that, because your widgets use Yahoo's API, the widgets can't be used for commercial purposes. It'll save a lot of time.
