Gotta love jackasses. Hey Zippy, the point of the article was that: "Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to two billion years of its EARLY HISTORY..."
Over time Venus climate changed which gave rise to the current one. It's an interesting study. The implications for Earth have to do with the consequences of heat build up over-time. Earth's oceans could evaporate over time if heat builds up to such levels.
