I'm not breaking up with Typepad but I did want to try out Medium. So I wrote a post about patterns, something I actually think is very important. I hope you enjoy the post but I also wanted to mention my thoughts about using Medium as a publishing platform.
First reaction - look to blank to me - where are all the WYSIWYG editor toolbars? Oh, they're all based on contextual action so they don't clutter the landscape when you don't need them. Cool.
Second reaction - this is nice. Almost typewriter-like in the sense of putting a blank page in the typewriter and having it stare back at you. Its uncluttered design really brings you back to the writing. Sure you can add an image (I do like how every post can have a 'cover photo') but picking out the right image isn't the heart of what you're doing. You're there to write. The font is super-clean and readable.
Third reaction - I need to understand better how to link Medium to Twitter or LinkedIn - maybe I can't and maybe that's part of the design - I just need to investigate that.
Overall reaction - I like Medium. I resisted for a long time but I like it. It's clean and easy and somehow the UI keeps me focused on the writing. Now I have to decide if I'll use it more....that would be a pattern. ;-)
