Hi Sims3lover,
Judging by all the views on your thread I'd say you have a really good following. I've been reading your updates, but I'm also guilty of not posting.
I try not to let posts or lack of posts discourage me because I really enjoy telling my sims' stories. I would encourage you to do what makes you happy. If you get satisfaction from posting updates then do it - but with the understanding that people may not always have the time to show their appreciation of your efforts. That doesn't mean they aren't reading or don't like your story, it just means they may not be able to post a reply for one reason or another. If you find posting updates is a lot of work and you don't enjoy it so much, then maybe you'll decide to only post about major events.
I, for one, hope you will continue to tell your story. The only thing I like more than posting about my sims is reading about other peoples' sims (preferably with pictures, I just love that!!). I'll be here reading even if I don't always comment.
Kat
