Well, the web technology is a pile of sh.t and in this case with the textarea you don't put your hands as deep in to is as you'd with the text input. That's how I interact with the web technology.

It's just amusing, that's all.

Prediction for the future:

1. Google implements auto-complete for one-line textareas

2. Web developers create textareas with 2 lines but hide the bottom line with CSS and disable the return key

3. Something so diabolical even I can't think of it
