It used to be good but not updated in nearly a year so no support for more than 140 characters. Lack of interest from developers as no longer reply to questions.
Twitter let's me tweet more than 140 characters, can't here... and no notification of interactions? or did i miss a feature?
Could do with foreign language translation tools, but please NOT Bing Translate. Even Google Translate is better...
My favorite Twitter client.
* supported for posting up to 280 character long Tweets
* supported thumbnails on instagram
