Scrapbooking, Stamping?

Ok who is involved in this? I have not done scrapbooking, but I went to my first stamping party. I liked it, but I am not quite sure that I get it. It seems like a lot of work to make cards when you can just buy them...
Anyway it did get me interested in scrapbooking...I would like to make myself a wedding scrapbook even though I have been married a while. Any tips on how to get started? I have no artistic talent.
