Works fine in Safari 3/4, i'd imagine chrome should be fine too as its also using webkit. Albeit with a different javascript engine.

Really the lagging IE bit may be more along the lines of "we are a tech site, our visitors most likely can use a decent browser that adheres to some semblance of standards". I admit though I don't use IE 7/8 so I can't speak to how well or not those browsers work. Too lazy to fire up vmware.
