Sadly many we enjoyed disappeared, as they found themselves needing to distance from the world of ponies with the fandom’s recent behaviors in the past few years.
However there are still several we happily enjoy.
http://lifeloser.tumblr.com/ Has such adorable artwork!
http://justplumsweet.tumblr.com/ Has made us laugh on many an occasion, though unfortunately it isn’t updated often, if at all now. The creator also seems a wonderful person however.
http://myponynews.tumblr.com/ Has been of such use to us for keeping up with all the lovely merchandise being made.
http://irlponies.tumblr.com/ An adorable blog of tiny ponies exploring the world.
Both http://g1mlp.tumblr.com/ and http://g3mlp.tumblr.com/ have been great for better understanding our long and beautiful history!
http://meowmeowparadise.tumblr.com/ Such a wonderful person, and talented artist. We have listened to her music as we worked through many nights.
