Why wasn't Friday's pro-mosque rally in NYC big news?

If you haven't heard about it, you're not alone. But note this nugget buried in an AP report late last night [emphasis added]:

More than 2,000 supporters of the project, waving candles and American flags, held a vigil near the proposed Islamic center's site Friday evening instead of Saturday, saying they wanted to avoid entangling the mosque controversy and the Sept. 11 observance.

You might recall that activists opposed to the construction of the Islamic community center held a very loud rally on Aug. 22; a rally that drew widespread media coverage. How many attended that event? Approximately 1,000, or half as many who attended yesterday's pro-mosque event.
