I'm a little surprised the behavior of Twitter's search get method.
Few weeks ago i created twitter acount for testing. I used search get method to parse tweets, like this:
http://search.twitter.com/search.json?q=netizencytest
It worked fine, but somewhere a week ago began returning empty result.
So, why it happened? It still returns empty result for this account. Maybe.. twitter banned parse this account for some reasons?
Another accounts return result correctly, for example try this one http://search.twitter.com/search.json?q=shymofficiel
