dont make a launch date, release it at a random day and hour, otherwise whales are gonna be pointing their hundreds Mhs farms when the coin launches 
This.
Seem like a good idea to me. Announce that the coin will be randomly launched between Feb 1st and Feb 7th, and when it is launched the announcement will be made here, in this thread. Also, make the block reward start out small and slowly increase (over the first week?) until it reaches its "natural" level. That should make for a smoother launch, I would think.
Also, I'd like to say: cute pigs, but totally ugly moustache. I totally hate moustaches. Go with the pigs, get rid of the child molester.
