I really liked IGoogle it was a great way to consolidate lots of information on my homepage in any browser. It is gone. You can't get back but there are a bunch of replacements you can try.
My favorite is one called IgHome but we put a list of a bunch of them from an article we found online on our website so you can check out that link to see other replacements for IGoogle and try which one works best for you. In any case IGoogle is gone and you need to find something else if you want that functionality now.
