After looking at all of the statistics of the “old” Webfeed Decentralized, I realized that even if they don’t allow customized templates, here at the WordPress.com site, it’s okay.
That being said, I’ll say that I never really had too many click-throughs from the “Decentralized” site. The ads that were showing up were never really that “targeted”, anyway, because I seem to jump from topic to topic, and never really focus on anything special, to get the targeted ads flowing in any particular direction.
I “am” going to be using the Qumana ads, here. If and when the WordPress.com site allows for customized templates, I might even switch over to a matching template from Webfeed Central. Until that happens, though, this is okay.
