I have a hard time picturing Lucius sitting on his bed scribbling 
away in the diary.  Just not a very manly thing.  I've always thought 
diaries were rather a "girly" thing, and therefore see how giving the 
diary specifically to Ginny could have been the plan because there 
was a chance that she would use it.  Give it to Ron and I wonder if 
it'd even have made it to Hogwarts.  I see it thrown in the back of 
his closet.
   
Adan, who never bothered with a diary anyway.

Carol responds:
Maybe JKR should have called it a journal--a lot of highly renowned
men, many of them British, have kept journals. That aside, though,
Lucius wouldn't be scribbling in a diary like little Ginny, or even
secretly recording amorous liasons with Bellatrix. He'd have known
that it was Tom Riddle's diary, and his reason for writing in the
diary (if indeed he did) would have been to discover its secrets. As I
suggested in another post, he may even have communicated with
Diary!Tom and hatched a plan with him for infiltrating Hogwarts. The
decision to give the diary to Ginny in an attempt to disgrace the
Weasleys was undoubtedly Lucius'. The ultimate goal of reviving
Voldemort via Tom would have been Tom's. Whether he would share such a
plan with the wily Lucius is open to debate. Tom wouldn't know him
personally (Lucius is a generation younger), but he could judge his
character based on the revelations that he's a fellow Slytherin and
one of Voldemort's Death Eaters, and Lucius could provide him with
information regarding his own future that he could never get from
Ginny. That might be enough to persuade Tom to reveal his true intentions.

Carol, who is not arguing that Lucius did write in the diary, only
suggesting that it's feasible
