Use of first person in a book

[Andrei Alexandrescu]

I'd decided to not use the first person at all in TDPL, but now I find 
myself a bit constrained by that decision. I personally think a small 
amount of meta-references and asides prevents boredom and brings a more 
personal note to the communication, but such devices should be used very 
sparingly and with care.

So I thought I'd ask a candid question in here. How do you feel about 
moderate use of the first person in a technical book? Do you find it 
comfortable, neutral, or cringeworthy?
