Social Wave Probs with Google Listings - Need an Expert

This year has been one big tech issue headache after another. First it was AOL's mail, then it was Yahoo's Mail. Now that AOL and Yahoo are being cool, it's Google's turn. Only this time it's not a mail issue. Socialwave.net seems to have almost disappeared from Google's search index. This one by far hurts the worst. It's completely killing our site traffic, which has dropped dramatically in the last two months.

I'm trying to get some answers from Google, but their non-existent support makes all the other support deptartments I've dealt with this year look like gold medal winners. You can't contact them. They contact you and they only seem to contact you when you're in gross violation of their policies. A couple of years ago, I did something I wasn't supposed to do and they came after me within a few days. This time around, I noticed that something didn't seem quite right with our index listings a couple of months ago. I first tried to contact them about a month ago and have since tried different routes to get in touch with someone and haven't heard a peep.

So, I'm hoping someone who has experience with an issue like this comes across this thread. If you've had experience dealing with a seemingly compliant site going from having 20,000 indexed pages in Google to <200 in the span of a week, I'd love to pick your brain.
