DeviantART has very much had an impact on me! About three years ago following a layoff (subject to recall, I was told) and feeling too burned out to really want to look for another job just then, I had a lot more time on my hands. For some reason I cannot remember I started looking up mermaid stories and found some, including some by Alveric2 at shifti.org. A few months later I found DeviantART and liked its combination of writing, photography, and artwork and eventually joined myself. Since then I have been continually diversifying, trying things I had never done before or at least not in years, and thinking of things I might yet do in the future.
Happy B'Day, DeviantART!
