I have been using Netvibes as my starting page. I like that more than iGoogle. Here is my collection of Sitecore RSS feeds. Collection contains about +25 blogs, Sitecore corporate news and Sitecore Developer Network articles and forum posts in RSS. There is also Google Custom Search for Sitecore on Sitecore related blogs.
If you have a Sitecore Blog or another useful resource that is not listed here. Please let me know
