Most of my edits are of the spelling/grammar type, since I rarely have time to write "real" stuff, but I also try to add content and weight to articles when I think they need it. I rarely look to create whole pages from scratch, but have started a couple of pages for subjects which I thought worthy. My Wiki interests run the spectrum from Christianity, Scotland & the natural landscape and demographics of the world.
I've been on Wikipedia since April 2012, and have for the most part enjoyed the experience.
