I had take a long break of TN for 3 majors reasons:
- I am an active member of 4 others french-speaking sites;
- english not being my primary language it is harder and longer for me to do comments like I want to give;
- the people you mentionned are not here anymore...;
But this year I took the resolution to post at least one picture per month on TN :)
TN stays a great site in my opinion because it let people from different countries, cultures, religions, etc to share a common love: the love of Nature. This is, I think, the power of TN over all the other website: its diversities towards the same passion: Nature Photography.
Even if the photographers you mentionned miss me alot, I know that new ones will fill the hole that some of us can feel right now.
