Other than the fact my links, and the names of some of the systems say otherwise, here:
liberal socialism
economic system representing a compromise between socialist planning and free enterprise, in which enterprises are publicly owned but production and consumption are guided by market forces rather than by government planning. A form of market socialism was adopted in Yugoslavia in the 1960s in distinction to the centrally planned socialism of the Soviet Union. A similar development occurred in Hungary during the late 1960s and early 1970s.

In the 1930s, the Social Democratic Party of Germany (SPD), a reformist socialist political party that was up to then based upon revisionist Marxism, began a transition away from Marxism towards liberal socialism beginning in the 1930s. After the party was banned by the Nazi regime in 1933, the SPD acted in exile through the Sopade. In 1934 the Sopade began to publish material that indicated that the SPD was turning towards liberal socialism.[9] Sopade member Curt Geyer was a prominent proponent of liberal socialism within the Sopade, and declared that Sopade represented the tradition of Weimar Republic social democracy — liberal democratic socialism, and declared that Sopade's held true to its mandate of traditional liberal principles combined with the political realism of socialism.[10] After the restoration of democracy in West Germany, The SPD's Godesberg Program in 1959 eliminated the party's remaining Marxist-aligned policies. The SPD then became officially based upon freiheitlicher Sozialismus (liberal socialism).[11] West German Chancellor Willy Brandt has been identified as a liberal socialist.[12]

By traditional socialism, we mean here the sorts of systemic changes associated with the Soviet Union and China, but also with European social democracy. By fascism, we mean the sorts of systems exemplified by Mussolini's Italy and Hitler's Germany.
The USSR lasted 70 years until its traditional socialism collapsed in 1989, while the PRC continues in its 65th year. Recently, the PRC permitted and enabled a vastly enlarged private capitalist sector. In that way, the PRC moves toward Western European-style socialism. The latter entails a largely private capitalist economic system: private ownership of the means of production prevails with markets as the chief means of distributing resources and products. The government owns and operates some industrial groups (perhaps the "commanding heights" of the economy), usually imposes fairly high taxes to fund considerable government services, regulates markets significantly and manipulates fiscal and monetary policies to manage capitalist cycles via an active Keynesian interventionism.
Finally, the liberal socialism article is terrible, and might as well be a stub article for social democracy (which isn't socialism).
Okay oh arbiter of such definitions, why not take it up with wikipedia? I'd love to see that argument :P But I'm sure that's beneath you...
