Could be a few reasons. I haven't been active on DeviantArt over the last half of a year, and most of these comics were made overtime, and I just uploaded them all at once. But I appreciate the sentiment, and maybe I will get more in the future!
I run my own site and I'm currently working on making a lot of blog posts about best comic strips for this or that. I always give credit / links and even feature the artist a little bit. Your comics are definitely more than good enough to showcase! (:
