I wonder if iWeb '09 transfers the entire contents of your site every time you make a change. iWeb '08 seems to "touch" (date & time stamp) most of the files when the site is published to a local folder. This complicates uploading only the updated files. It would be great if iWeb '09 had the smarts to only upload what was truly modified since the last upload.Working with multiple web sites in iWeb '08 is also a pain. Hopefully that has improved.
