Search for Outstanding OS Speakers

[Keysguy]

I wasn't sure where this topic fit so mods please feel free to move if there's a more appropriate forum.

So, I've volunteered to take on a role of which the focus is obtaining speakers for our OS meetings.

Although I really only need to find them for about 6 of our meetings over the course of the year, our remote and VERY expensive location really creates some challenges. I have some ideas with how to deal with these issues and will pursue those but what I'm really curious to hear from all of you about is....

Who have you heard speak that you were super impressed with and would recommend?
What was the topic?
Did they bring plants for sale?
Why were you impressed by them?

If there are sensitive issues you'd like to fill me in on, please feel free to PM me.

Thanks in advance, I look forward to hearing your feedback.
