I never left deviantart since.... 5 years ago (currently). I started there after Flipnote Hatena, and haven't left since. It hasn't treated me bad, and the only thing I've had to worry about is making sure my art continues to grow and thrive properly. Besides, the translation from deviantart to tapas (in terms of comics) has and hasn't worked at the same time, but I never had a true reason to abandon the site. xD My art is harmless and so are my comedic or action stuff, so anyone is free to jump in, read and have fun.
To be honest, I used to upload EVERYTHING on deviantart. Comic strips, drawings, even literature. I only decided to spread things out so my page doesn't look cluttered. Looking back, it makes it feel a little barren outside of making new drawings. Maybe deviantart is making a comeback, but that'll be a big wait, and see.
