Should I bother?

Short answer: No.

Long answer: Have you looked at the ads available? Many publishers think that the conditions often are not serious ($0.01 per successful transaction?) and not worth the effort. Even for those ads that look attractive I strongly recommend to calculate the necessary number of clicks and conversions before coming close to your PPC eCPM. Add to this the unusable user interface, and some of the products' other quirks, and you'll probably come to the conclusion that, no, it's not worth bothering.

YMMV, other publishers may think differently.
