However, I will say this: I'm a wordy bastard, and I appreciate that Twitter enforces a very strict limit on brevity. Learning to say what I want to say in 140 characters or less has been...interesting. I find that if I have an idea I want to Twitter about, I usually have to edit it multiple times to bring it down to 140 characters. It's good writing discipline.
A recent example: "Between having a brain optimized for finding patterns (even if they don't exist) and confirmation bias, it's amazing we understand anything." Number of characters: exactly 140. Number of edits to fit it in that space: 3. Brevity is hard, but sometimes squeezing out the extraeneous stuff makes the idea more accessible.
