Firstly, Photoblog is an amazing site and the team back there is doing a great job to keep this place nice and clean. Kudos to you all.
However, I feel it would be nice to add an option to be able to follow or track the entries made by friends.
As in for example there is some Mr. X and I generally like the entries of him and i tend to check out all the entries posted by him. So i just register to follow his posts and every time Mr. X adds a new entry I receive a notification on my homepage saying "Mr. X added a new entry" or something like that. This saves me the efforts to go to the friends list and check the entries.
This may or may not be limited only to friends based on the policies that you follow at Photoblog.
Also I am not sure about how much would you all appreciate this thought nor do I know if we already have this mechanism in place but I would love if we can have something like this in place.
PS - If we do have something like this in place then do educate me I am kinda new here...!
