Julio, you raise a good point - posts and topics on this forum continue to get quite a lot of views.
In this past when this has come up, or when I've spoken up and reminded "lurkers" of the need to contribute in order to keep this forum vital, we've had a surge of activity... lurkers speaking up, all kinds of people creating new topics, and for a while everything is buzzing. That proves people are reading. For whatever reason, though, many people seem content to just read the topics, perhaps seeking a little quick diversion during the day, and don't feel motivated to post anything.
It isn't that I don't wish more people would post, but I don't think I'm really helping the forum by nagging or pushing people to contribute more. I wouldn't want to visit a forum where the administrators constantly made me feel guilty for lurking.
Once in a while, a topic comes along that really gets people fired up. At times like that, we see how many people are actually reading.
