Rob Ault: Since E. B. himself uses the space, I will too, but I don't mind the no space option.

Yvonne Klein: I tend to drop the puncuation: EB White.

Tom Kreitzberg: P. G. Wodehouse is one of mine.

L. L. Thrasher: Two names, two words, even if they're written as initials. Therefore, use a space between them. However, if a person uses his initials as a name, then it's one word, no space needed.

Yocheved Golani: Without spacing, it seems like a typo.

Joe McGavin: I always thought it was e.b. ... or am I thinking of e.e. cummings?

Mark H. Bloom: Initials -- like the "U.S." -- can be condensed.

Carrie Garbas: The spaces don't serve any comprehension purpose.
