As far as I know, there are only maybe 2 or 3 people showing up for the Kernel Summit and not attending OLS. The rest are staying in Ottawa for the duration. I don't think that hurts us at all. The theory was that by holding the Kernel Summit before OLS, more people would attend both events, although I personally think that the Kernel Summit benefited a little more from this arrangement than OLS did. We always ask the attendees what they thought of the event, and usually they say, "too much content...brain fried!" and I guess that's a good thing. I wonder what effect the KS will have on their responses.
As for the negative vibes aspect of it, I am completely unqualified to comment. So yeah, you'll have to take that up with someone more knowledgeable than I.
