1) We have a democracy here. Unless you try to scam everybody of their money (De La Rua-Cavallo), there will be no revolution. Get it? Democracy, like in Europe or the US. If you are Argentinean, in October you can vote (and you don´t need to register before).
2) Qadaffi (or whatever the westernization of his name is) is not in Venezuela, obviously.
3) Chavez was elected in proven fair elections, with international observers in place. Elections continue to have place, and the institutios are there, this is not Germany 1933. The opposition tried to take himout with a military coup supported by the US,they failed. Whatever your ideology, you cannot continue with the dictator thing, because he is not, unless you think that Bush was a dictator. Authoritary and demagogic? Yes. Dictator? Nope.
4) Qadaffi and Chavez are not memebers of Couchsurfing. Julian Assange is.
