Did you know that you could use Mindjet’s MindManager as a news reader? I’ve been using MindMaps for some time now, but I just found out about it today.
I cannot say that I’m completely satisfied with its performance (it does not recognize some of the feeds I tried) but it has much potential – they might have already done some progress in version 6 (I am still using X5). This could lead to totally new ways of blog reading.
You can download here a MindMap with some of the blogs I am reading currently:

Or read about MindMap and blogging at The Mindjet Blog.
