I'm gonna go out on a limb and assume that a few people who work at google know why.
My only concern is their lack of interest or respect for one's privacy. Today I read this article and it made me realize that they don't really care at all about the people that use their services.
Hahahahahah! Meniacal laugh. No, you're not. You are not for sale and neither is Hubski. So long as we can support the site financially, we will. To date we do so out of our own pockets and get a small amount subsidized through your donations. Emphasis on SMALL. But, we don't even collect any rela vent info on you all and we don't want to. Ever. We have other things we have built and are building to make money. Hubski we built as if it were an art project. It's here for everyone's enjoyment.
