kinda. Libertarians, as i take it, see that power should not be concentrated in govt -- that the people should have power -- more importantly, the individual. A socialist recognizes that there are other sources of power, for example, wealth, which are fundamentally undemocratic (even more so than, for example, a democratically organized govt) and can be used to deprive an individual of his liberties. Its how some solve the paradox that libertarians don't think its ok for everyone to get to together and tell someone what they can or cannot do (ie, democratic govt) but an individual with a lot of economic power can tell others what they can or cannot do (ie, a monopolist, or even better, a monopsonist -- a single buyer). I prefer the term anarchist myself, i know there are nuances in the "definition" but i haven't gotten to them.
