Steve Rubel is concerned that Google might kill Google reader because it is not profitable. I had always assumed that Google was collecting and aggregating reader information and selling it.
For example, which zips code have the most Google News Alerts on e-discovery? What other key words do they have? Fraud? Maddoff? Sarbanes-Oxley? XBRL? Of those who have Google News Alerts on e-discovery, what do they have in the Google reader? Gabe's Guide? Washington Post? Blog of the Legal Times? CNET? That would be very valueable to have.
I trust that Google limits the number of queries in such a way that no one would be able to know what I had in my reader.
Google as an advertising vehicle is valuable, Google as market research is pure gold.
