Why Dean as Ginny's Next Boyfriend?

JKR could have chosen any boy from any grade and any house to be 
Ginny's next boyfriend.  I think it is significant that JKR chose not 
only a Griffyndor as Ginny's next boyfriend, but also one in Harry's 
grade and in his extended circle of friends.  This will mean that Harry 
is "exposed" to Ginny's love life much more so than he has been in the 
past.  He's been able to ignore it before because it hasn't been under 
his nose, but now . . . .

I can see Ginny and Dean sitting closely on the couch by the fire in 
the common room or studying at the same table and then Harry finding to 
his surprise that such scenes bother him.  He may even overhear Dean 
talking about how wonderful Ginny is and feel a pang of jealousy.   Or 
perhaps Ron will drop not-so subtle hints to Harry about how he wishes 
Ginny would find a different boyfriend than Dean.  (Not even to mention 
if Dean turned out to be the HBP.)

Does anyone else think the choice of Dean is significant?
