I enjoy exploring what's possible with things that seem limited. I wrote that in a reply earlier today. There's something both challenging and inspirational to work within limits.
It's also a great creative catalyst. Fewer distractions, more focus.
Take this post for instance. Written in the Wordwrap textfield. No buttons to format the text, upload images, or add links. Just a blank page staring back at you, wanting to be filled with words.
Sometimes, that's all you need.
