That's strange. When I skimmed over that Wiki article, I totally missed the part that talks about persistence, even though it's the second paragraph:
Is it just me (my wife will tell you I'm blind when things are right in front of me, so it may well be me), or should this be highlighted more clearly in the Wiki entry?
@JMichaelTX - What do you think? It's just me, isn't it?
