Start? Yes, Start.com is a Microsoft sandbox initiative that looks similar to Google Homepage with a little SharePoint thrown in. I'm not sure why this exists. If it ever sees the light of day, it will probably be in the form of consumed features added to My MSN.
It's too bad you can't replace the Yahoo! search bar with Google on My Yahoo!. Or even better, some sort of standard widget such as Web Parts that could be embedded in Yahoo!, Google, MSN, DotNetNuke, etc. so you can choose your own start page with EVERYTHING you want.
Welcome to my tech blog. My primary focus is development but I did spend a few years recently on the networking side. You will find that most of the items relate to Microsoft based technology. It's not that I have anything against Java, Linux, etc. It's just not what I do. If life were Star Wars, I would be a Storm Trooper.
