I lurk more than I post. There are a couple reasons why-
1. I feel like my opinion has already been expressed by someone else, hence, I have nothing to add to a thread.
2. Limited time- I have a family, work two jobs and lot's of other responsibilities... I don't even have time to read all the threads, much less post.
3. I've never felt compelled to. I've always felt that this was a place to "come as you are". There are a lot of different personalities, experiences, styles etc here. No one should ever feel forced to do something they aren't comfortable with for whatever reason. It would make me sad to think that anyone who doesn't post but reads every day (like myself) feels that they are less than anyone else because they don't put their 2 cents in.
