I'm using "from:username", but not getting any new results. I noticed when I query the user on twitter (@lonnamarie), the latest tweets are from a year ago (although this account actually posts every day). When I try a more popular account (from:jetblue), I get some results.
Does the twitter firehose have something to do with limiting the tweets available for lesser known accounts? If so, is there a better way to use your plugin to get all tweets from specific user(s)?
