Chávez and Twitter

Venezuela's president twitted
98 times in August of 2011,
30 times in September,
10 times in October,
9 times in November,
4 times in December,
3 times in January and
0 times in February up to now.
What's the matter?

The Chávez-controlled site of the National Assembly says there are 200 state employees checking out what people ask to Chávez' twitter account, as Venezuela's government is so screwed up everything has to be "delegated" to the head of state. I wouldn't be surprised if some of the tweets "by Chávez" are from an authorized employee, but so far, that is not happening either.

Is Chávez tired or is he really sick and no one has thought about  letting an employee pretend to be Chávez?
