First of all, glad to see you here and welcome!
Listen value comes in all shapes and sizes, I remember when I joined last year I saw some people attempt to blog but finding it wasn't for them, or they didn't feel they could create a high enough output to make an impact.
Then slowly people started to find their own value niches. Look at someone like @firepower who did a few nice blog posts, and then decided his talents were best served behind the scenes, now he is a major part of this community.
Different strokes for different folks :-)
