I took the 7 sites and closed them down. I waited a bit over a month for all the content to be removed from the index and the cache. I bought an aged PR 3 domain with great links and a generic name. I then had my VA's go over each article and make them even higher quality. I added more videos, pictures & diagrams. I also took some old articles I had lying around that I never used and did the same with those. I then took all of this content put it on the PR 3 domain and made this a general "about everything" kind of blog. Did a bit of high quality link building.
Its been a few months and that blog now is getting loads of traffic and tons of long tail traffic that the original sights weren't bringing in. This is a good way to salvage content from sites that have been destroyed. This works well for people like me who have a good amount of sites. Just a suggestion for those feeling some pain today.
