The latest casualty in my running battle with our sysadmins is Bloglines: it has been added to the proxy server's blacklist. Never mind that Bloglines can be used to read "productive," work-related blogs as well.
The good news is that Newsgator seems to have escaped this blacklisting (the proxy server probably blocks any URL that contains the string 'blog'). I have therefore dusted up my Newsgator account and have brought it in sync with my Bloglines subscriptions.
Though I prefer Bloglines over Newsgator, I am beginning to like 'Gator and am getting more and more comfortable with it (either that, or I am making a virtue out of a necessity. Take your pick).
