First, I've used this domain for many years as a resource for my high school students, with links to notes, the week's schedule, assignments, etc. When I retired from teaching, I decided to keep my name-sake site and make it personal.
Gregwieland.com enables me to keep my memories, favorite photos, and things I care about in one place, a place that's accessible from anywhere at any time. So part of the reason for this site is to consolidate information in one place. Just as important, it enables me to share what I like, and what I think is important, with others.
Besides all that, developing and maintaining a website provides me with a creative outlet. It's fun.
