The new version of Viral Instigator is out. For details, see their blog:
I am waiting for them to answer a few questions about this, so I’m not posting a full review yet. I have a few concerns.
Since now the only way to post to these blogs is using VI’s internal poster, that means that you can’t access the blogs. So you need to maintain your monthly membership as long as you want to post to these. Does anybody else see the downside to that? 
Anyway, I’m waiting for clarification of that. The way this program appears to me now, is that we are basically just renting websites from them.
On the bright side, their WP installer should be out in the next week!
