If you happen to have found my blog, and are an old follower of mine; I may return to Tumblr eventually, but for now I'm taking some time away from Tumblr. Re-follow if you feel like you should, I am making no promises to continue my blog at this stage. There's a decent chance it will happen eventually, though.
I have not left the fandom, I am still a brony. However I am simply less involved with Tumblr for now.
