All my sites dropped (I get bored of hitting next before I find them) between this morning and this evening. They all target different travel destinations, are all legit in that they have good content, incoming and outgoing links (and deserve to come up on the first page). One of them has been #1 for the last year.

-I change up the SEO of them every time google spots changes and repositions them... maybe that has something to do with it.
-I add content to them often (once a week) and change around old pages
-I don't interlink them (maybe 5 links total when related)
-I have one site (for my business) that links out to all of them
-it seems odd to me that google would care the sites are all owned by the same person (nothing else explains why they were all dropped at the same time, because they were all optomized in a different manner and are completely different sites)

In response to Tom_D's initial post: I had a site that only the domain name showed for 2 months, and one day it snapped to normal.
