I haven't seen that yet, but I agree. Also, "ewe" is already a different word.

I guess the only argument for it is that the e, w, and r keys can be typed with one hand on a computer keyboard, but you need two hands for y, o, u, and r. That doesn't buy anything on a cell phone, though.

Seems like the increase in mental effort to decode ewe or ewer outweighs any possible keyboard convenience.
