‘jti’ seems simple to type & its unique enough. Changing it won’t get you anymore attention.
Besides, no one ever says ‘come in jti’ here but they say ‘come in handy’ a lot.
Oy – what’s wrong with three-character names? 
Actually, I posted a similar OP not all that long ago, but decided to stick with who I am, at least for now. YMMV.

I gotta agree with the whole “I get posters with initails for names confused” camp.
