It seems grouping and counting, then ranking the topics returned by
Daily and Weekly trend API does not give the correct top topics shown
in home page of twitter.com. Can anyone tell me how the Popular
topics today and Popular topics this week works in http://twitter.com/?
i.e. after parsing http://search.twitter.com/trends/daily.json, topics
are simply counted and ranked. however, the result is about less than
50% accurate to what is displayed in the home page. Anyone knows the
actual algorithm used in the site?
the front page is a curated version.
I just noticed yesterday that Today and Weekly list no longer have
hashtag topics? Am I correct on this observation.
yup - the today and weekly list, on the front page, has had hashtags
stripped out.
