I agree with you that web bot can be all over the place and timing for events can be way off but It seems like the economic predictions have had some gems lately. For example, months ago the web bot predicted an italian banking crisis will quickly spread into the rest of Europe and collapse the banking system there. While this hasn't completely happened yet I have to give the Web bot kudos for getting the italian banking crisis right way before anyone else was talking about. That is the type of info I value from the web bot.
