Things I always enjoy seeing on everyone's posts:
Obviously, photos of outfits! And I like to know things about the whys of why any of us make the choices we make: circumstance (season, weather), purpose of the outfit (work vs. play), your mood when you selected it, the happiness factor once you put it on.. I have gotten so many inspirations and ideas from the WIW posts on these forums.
The other thing I love are photos of clothing capsules! I am fascinated, thrilled, and enchanted with capsules. I guess on the inside, I am always that 12-year kid going shopping for a back-to-school capsule, and taking pictures of potential outfits. There have been so many brilliant ideas and insights on these forums. You have all really shaped how I choose my outfits - and how I edit and purge my closet.
