Dropbox is an application to share and store files online. I have been using it already for some time while it has been in private beta. Files that are put in the Dropbox folder are automatically stored online and can also be accessed through the web interface. Today Dropbox finally launched to the public.
Flickr rolled out a sneak preview of the new Flickr home page. After switching to the new interface there are more photos from contacts and photos from groups on the home page. Users can minimize the sections they are not interested in. Moreover there is an activity stream showing the recent activities on the photostream. Pro users can access statistics directly from the home page now. More information on the new design on the Flickr Blog.
