The 500 character limit feels restrictive to me. Often, it's not enough to express an idea, so I end up splitting a post to several.
I'm thinking of increasing it to something ridiculously large...
The limit is especially painful when I write a post using a phone, when it's important to "flush" the stream of ideas.
It's less important when I type on my laptop, since exiting and splitting is much easier.
For Twitter-style impulsive writing, character limit is a bug, not a feature.
And yes, I do want to be able to flush my ideas spontaneously. If I want to think of it, edit, rephrase and give a lot of attention, I would write a blog post.
