At TechEd this year, I presented a session where I presented my top five pet peeves on the web, the biggest and easiest problems to avoid on the web. With how easy it is to share content on the web, I felt that these top five things were the best and easiest to get rid of.
In order, I felt they were:
5. Unprofessional Site Design
4. Lousy Content
2. Inappropriate use of Rich Content
1. Not Being POSH
I've attached my slides below, so check them out, and let me know what your pet peeves are!
