Points de vue
Since three weeks, Jesse has created an archive page for some weblogs, more or less dedicated to DotNet (and/or Microsoft).
It's a little bit like the DotNetWeblogs main page: posts appear one after another, without author classification. This principle has the advantage of giving a general view for all that weblogers are saying around the Microsoft's sphere.
I like this kind of view and I even think it's a more user-friendly way than the three-panes method used by most of recents aggregators (at least those build with .Net). It's almost a pity because they only allow showing one post at a time. And you must use tricks (like spacebar) to jump from one unread item to another.
Whereas with the "Blog Activity" system, I can directly view the full posts details and browse them simply by using my tablet's wheel (or your mouse's wheel). One other benefit is weblog's conversation. It's easier to notice and follow them with a listed display.
In my opinion, that would be great to have an aggregator which would provide a similar presentation: I will set up my blogroll and get a main page with all posts in a listed (and detailed) way.
