Since 3/26/09, it appears something has broken the "Publishing to MobileMe" portion of iWeb '09 for lots of people. I am trying to figure out if anybody else is seeing this problem here and know of a workaround and/or fix. Basically, if you make any single change within iWeb, it's wanting to republish your ENTIRE site each time instead of just the change. Every page turns red to be re-published up to MobileMe. Talk about hours! Ugh. I found the following discussion(s) over at Apple, so this appears to be more widespread than I thought effecting a lot of people....
