It really is difficult for the larger communities to drop comments on every post -since they have so many entries usually!!! But I know exactly what you mean about it making a big difference - because it does! :)
which of course - is why I had to stop by and say hi - and appreciate you! hehee
Not sure if they'll ever be able to get comments on all the posts as leaders, but maybe everyone who participates is required to leave a comment for someone else? kinda like how inkwell does! then even if its not coming from the leaders- at least it's coming from the community!
and i love the topic that you chose at the end... generosity is a beautiful thing!
