Both are mine, but after some time blogging I now understand how to distinguish between the two. The Tumblr is mostly things I see on Tumblr. There is a great company there too. The WordPress, however, is a lot more personal and intimate. I only do write my own posts there and this is what I really am and what I live for.
The cross-posting is set up from WordPress to Tumblr (but not the other way round) so all you see on WP will sooner or later appear at Tumblr tagged ‘personal’. Check this tag if you are up to a more serious content.
I love Tumblr for the pace and visual part, but I also value WordPress for the easiness of commenting, which is free and open to anyone regardless of any registration. I do read all messages, comments and questions everywhere and do my best to respond. Feel free to get in touch.
