The other aspect of it is that people feel it is free; they're not paying every time, it's not like putting coins into a telephone. They have this concept that it is free, but of course you have to make money to function and to do as well as you do.
I noticed in some of the descriptions about the company, it says that Twitter does use cookie technology to collect additional website usage data and to improve its services. Could you outline for people so they really understand what your business model is? There's nothing wrong with that, and if it weren't for the fact that you could make money, it wouldn't happen. Could you give me a bit of background as to what you use and why you use it? Then perhaps people can get a better idea of what this free function is all about.
