http://www.blogreviewed.com/ (In beta - I believe i saw it on HN previously but can't find anything searching now) is an attempt at this. I think the product needs a lot of work - the tips on pitches and the way they evaluate sites all seem to have been done quickly/formulaically. The idea, as you mention is a good one. If they could improve the execution it would be useful. It's not a common app, but it makes pitching a repeatable process in an automated way (in theory).

I don't know if it was random or not, but it seems like they start with really easy (and in often case worthless) targets and then just work you up to say a VentureBeat. We (GroupTabs) had already been covered there, along with a couple other of their suggested pitch spots - so they definitely are not looking at that, which would be a nice feature.

That said I'm not sure a common app would really work. If you want coverage it's more than pitching the right publications, it's pitching the right people there.
