So how many people have stopped feeding WU/Intellicast since they have merged? I'm thinking about stopping my data to WU.
Absolutely, no way for me. This is because in return for my data to WU, I make good use of 9 of their stickers, radar and weather maps on the main home page of my site. I am usually happy with it.
Maybe people who don't like sharing data for free should offer selling it to companies like WU, or which ever company whose practices they respect. They would probably say, no thank you, but you never know until you try.
