I suspect those (the House capslockers) were the ones who started the trend, and interesting enough they're famous for their wanks. Their retina-burning, epilepsia-inducing layout doesn't help either.

...ironically, the CLAMP capslock comm seems to be made in order to wank.

It could be worse. The day someone makes a StIcKyCaPs comm, then we'll know the webapocalypse has come.
