True. It was also no Katrina.
If Issac can get organized over the next twelve hours or so (which seems likely), then it will probably slowly strengthen; I'd say it has a 5% chance of reaching the kind of intensity that Katrina had at landfall.
One difference between Ike and Katrina is that the good Texans of Galveston got busy (like the folks in MS and AL after Katrina) and started rebuilding their city instead of whining incessantly and wanting someone else to do it for them.
