I actually think it's easier to get the items from lurking than posting... I couldn't seem to find any good threads to post in so I went looking around in old threads for the eggs and ribbons... where I DO feel that the gold eggs come a bit more often than the ribbons since you need more ribbons to make the eggs than you do of the eggs (needing 2 red ribbons for the crossed egg) so the only thing I'd suggest is maybe increasing the amount of ribbons you get by a teeny amount since you can't trade in plain gold eggs for anything I'll have a bunch of them leftover.
But as I said lurking around in old threads that LOTS of different people have posted in, like old announcements and stuff has made it really easy to gain them for me... they may be slower to get than the eggs from posting, but you need less of them for the set of items from those eggs, plus the fact that you get 10 of the other eggs when you trade them in makes it seem pretty fair, on average I found enough eggs and ribbons to trade in for about 50 of the other posting eggs per hour.
All in all I LOVE the event and I LOVE the items :D and I'm enjoying it so much better now that the lag problem is fixed. THANKS EMY!
