If I didn't care I wouldn't be here.
There are over 20,000 members on this site. If we each took the full amount of time to spend with each member that would be wanted or needed, we would never sleep or go off line *LOL*
You fit in, you do matter but as I stated... there are over 20,000 here.
Personally, for me, I try to answer as I see a need and spread support around as much as I can. I may reply to 20 of your posts or I may not reply to a post for another 20 days. Many times it is a matter of who is here and asking what when I show up.
Yes pity parties happen with me from time to time as well but I have learned you get a sore butt from sitting on the pity pot for long times *LOL* I get myself off as fast as I can.
So as far as how many replies ... timing, who is around with an answer at the moment, and many times... a great answer is given, no need to reply further is a reason replies stop coming.
You do matter and this place is filled with many people who do care.
