My favourite Social Software enabled web browser FLOCK has just been updated. A few changes - some good, others I prefer the 'old' styling of v0.5
The MyNews option is a reasonable RSS reader, but I think the WizzRSS extension is more fully featured.
I preferred the old style Blog editor & Flickr toolbar integrated into the main window of Flock - now they are separate popup windows. I suppose you can m,ultitask better that way - will play & see what I think.
The setup wizzard is rather buggy too.
