[Plugin: WordSocial] Twitter without #hashtags

Good morning.
I’m publishing my posts with categories and tags, but the #hashtags aren’t going to my tweets, as you can see on my twitter @eczandona : https://twitter.com/#!/ECZandona/status/182465693546070017 and the post on my WordPress blog : http://escritoriozandona.com.br/wpress/?p=502 . The options flags are checked on “Twitter Settings”.
Tweet format: %title %link %comment %categories %tags via @eczandona .

There’s anything I missed?
