I find that I get a flurry of activity after each new item is posted. At 1 time I had posted a bunch all at once and then felt there was a letdown (for me as well as out there!) b/c then there wasn't quite as much action going on after I had posted all these new styles. So, long story short here, I do tend to post new items as I go and not wait for a whole group. Spreading it out if possible seems to work better for me so I do tend to post new items as they are ready.
