Now that we have all new Flickr my way to use it has changed. In the old school version I was almost never using Flickr homepage but I was always in my photostream page. Now I am using Flickr homepage a lot. From there I can see the new shots from my contacts (and also straight possibility to comment and fave them), comments for my shots (and other’s I have already commented on), glimpse of my groups and some shots from Explore.
I find the new Flickr homepage better than the old one. At least I am using it now way more than before. I think the main problem with the new UI is in the photostream page which is lagging some useful information it has in the old version. It is interesting to see how things evolve from this.
