I will probably begin doing this but i will say-- in the past it was not a hurdle at all, and i got many interviews and a few jobs with this name. I have had about 10 interviews in the last year, going to 4th rounds, and nobody suggested it was a problem. my ratio of landing interviews per applications i put in parallels what I am hearing/reading from all other developers on the job market now. I don't strongly suspect my one-letter last name is a huge culprit here, but after a year on the job search and willing to try anything, i may begin applying with a pseudonym
