Ok, to relieve you of the suspense, I shall give you a simple answer: Yes, I will commit to DeviantART and it will become my secondary portfolio.
This decision is 99% because of how active the DeviantART community is and how comparatively easy it is to have your works exposed to the community. I am still in shock at how my "Misty Yangshuo" photo is reaching 500 views and has already gathered 70+ favs, something that I have never been able to achieve on Flickr. In fact, my best record on Flickr is 2 favs, and 50 something views. The other 1% is purely because it seems like a novel idea to have an alternative portfolio
However, there is one major thing that has stopped my from replacing my Flickr portfolio with DeviantART's. That reason is because Flickr is designed for photographers, so the community is photography-oriented and the tools, website and design are solely designed for photographers. Examples of DeviantART's failing at this is its light green background, which can potentially disrupt the photo's mood and colour scheme. Also, the upload process if unbelievably slow. One at a time? It's mandatory to assign a category to every one of your works? No using other languages and grammar symbols in the title of your work? No geotagging? Oh my! Nonetheless, I will try to post most of my works published on Flickr.
