Yesterday I was re doing our process for ideas and alltop was a part of it. Now I have also known it was a bit spammy (some of my grey sites are featured ) but now it seems way too bad. You have places like new York times next to random adsense blog x. Guy kawasaki needs to really start giving some sort of influence ranking or at least culling the total crap ones.
Lastly, it's important to remember that paralysis by over-thinking is a real issue some struggle with. There's no pill for it (yet). Predicting perfection is a fool's errand. Get as close as you can within a reasonable timeframe, and prepare for future iteration. If you're traveling through your plan and determine a soft spot at any time, simply pivot. It's many hours of upfront work to get your strategy built, but it's not too hard to tweak as you go.
