I have had such fun this morning playing with the 2 customizable sites. I really like "iGoogle". Altho' both have access to the same offerings I liked the look of the "iGoogle" page better. I was able to use my own pictures to create a theme, which was just awesome.
I do think that the option of offering a "public" page for library patrons makes "netVibes" a better choice for library use. Putting links such as "Facebook", "YouTube", etc would be really helpful.
Our library does have a common home page for our patrons with information about schedules, programs, and fund raisers. I have included our page address so you can take a look.
