I love
Erica!
Erika is good too, but I prefer it with the C. Same way I feel about
Eric /
Erik, only I like
Erica more than I like
Eric. I think the usage was sudden, short, and intense enough that it won't make a comeback very soon. Too much of a "mom" name. But neither was it such a fad name that it'll die out.
