This means you can actually have a discussion, rather than just a load of one-off comments.
that's true.. sometimes knowing who you're talking to makes the discussion more meaningful
3. Zagat is focused on a narrower market than Yelp.
not only that... zagat editors provide the service of compiling and sorting all the consumer reviews into tidy lists printed in a book. yelp is just a big mass of opinions per location with a few limited sort options to wade through the mess.
for some reason athletic shoes have a focus on form rather than function.
I vote for shoe laces cuz I gotta look good when I work out... cuz I work out to stay looking good...
banking on the current "mood" means he's actually inflating the dangerous cycles of emotionally driven, short-term investment decisions rather than making any kind of long-term decisions.
emotions might help make pretty good (and quick) decisions in the short term, but it's true, aiming for long term cannot depend on emotion. it has to be based on solid, concrete data. for example, i could choose to eat pepperoni pizza for dinner based on emotional responses to the smell. however if i had a goal of becoming vegetarian, i should not be choosing to to eat pepperoni even if it smells good.
even if twitter feeds seem like real data, sentiment analysis is aggregating emotions of a crowd. Justin Bieber might be a 'hot trend' now but you cannot assume his popularity will remain for generations to come. Many fans like him for qualities that cannot be preserved for long (i.e. young face, young voice). Choosing stocks based on hard data is like admiring a singer for inherent qualities, like talent.
