I was surprised (and excited) to find this out. I’m not a huge twitter user primarily because twitter here in PI is not yet mainstream (I wish for the day where Telcos would start integrating Twitter on their services). Anyway, so I tried blu: the twitter client for Vista (and Win 7), I was blown away by the UI. I’m using thwirl as a twitter client, which is already amazing, but blu makes twhirl UI a joke. It has a very, very, very slick user interface and its easy on the eyes. It blends perfectly on the whole Aero glass interface. And I’m glad that it’s built using WPF and .NET Framework 3.0.
