I love YPN, don't get me wrong, but there is nothing more frustrating than the ups and downs we are seeing with this beta.
I think for the most part the only consistent issue is late reporting. You never see a daily report until the day after all amounts are calculated. you can =see an estimated daily balance which is nice, but those of us who constantly check our Adsense / YPN stats hate that there's no details behind it.
The daily balance brings us to our next major peeve. Today is the 3rd day that we have seen "No Activity".. all day. Yersterday it was frozen wioth "As of 5:15PM" until about 4AM.... The idea,for those of you dont know, is that they deliver new results every 15 minutes, which is very nice because unlike Adsense you can see exactly when that last total was calculated.
All in all High payouts over low CTR are goiong to win me over any day of the week, however, as I stated tbefore this beta is absolutley not for the faint of heart.
