Above all, do not weigh them on the lower side just because they took the first step to sign up publishers like me. If that's running in your mind, then please chuck it off!! They wish to serve quality ads to their advertisers. So, they are fishy and want to be more specific in approving blogs to their database.
They pay through PayPal on weekly basis and the minimum amount to cash out is $25. More over, the site includes a featured listing (VIP blogs) where in, only the best blogs under each category are displayed to the advertiser. Once, you get into that list, it is clear that some day or the other, an advertiser would approach your blog. Before you sign up, ensure that your blog has enough content and reasonable traffic so that, your blog has a higher probability for approval.
I would say, this site is very similar to BuySellAds excepting that the procedure to approve our blogs is little different. The site clearly states that, "Acceptance will be based on: original content, number of readers and user engagement, rather than Google PR, Alexa, ComScore and other marketing analytics." Therefore, no harm in trying. Just give it a shot and share your views via comments!!! Don't forget to let me know, which website generates more penny for your blog now:)
