The new ads you see at the top of the page and in between posts and comments are SBN-network wide ads. They are a work in progress, meaning they're still working to integrate them better into the site themes.
There's already been some negative feedback on other sites, some of it relating to different browsers and screen resolutions, so if you're experiencing any difficulties or have any other feedback, positive or negative, please leave it below. The SBN execs no doubt will be combing through the sites looking for feedback.
One thing to keep in mind, though, is that all of the SBN sites are free for readers, and all of the bloggers are doing it for free because they enjoy it. (Yes, there are some ads and such on the sites, but I assure you, they don't pay much. So far, I think I've received one check for five dollars and change b/c somebody bought a t-shirt. Woo-hoo!)
Anyway, SBN foots the bill for hosting, site set up, tech support, etc., so they need to recoup their costs.
Like I said, leave your feedback below, and thanks for reading.
