Periodically, I click on a link to a news article, and am taken to a redirect that asks for my zip code, date of birth, and gender. This is to "better serve you (that is, me)".
How is this going to better serve me? What information does the site glean from that nonsense that isn't better gleaned by checking to see which the most popular articles are? It seems simple to me. To find out what your readers are interested in, find out what they're reading. Nonsense about where they live (or don't - I amuse myself by posting blatantly false information) and such isn't nearly as important as what they're actually reading, is it?
