Well, if you do, Salesforce.com would like to hear about it.
The SFDC IdeaExchange, has been up and running for a long time now. It's a place customers can share their ideas for feature requests with the community to solicit feedback and votes in order to try and get them higher up on the developmental "to-do" list. It's really interesting to have this kind of visibility into their feature request world, and the amount of detail and work some of their customers put into the feature requests that they post is pretty impressive.
SFDC has created a Dreamforce portion in the Idea Exchange, in order to solicit input from the community on content at this November's event. If you are a Salesforce.com customer you can vote on the presentations you would like to see, or if you have an idea for a presentation you want to deliver (that is not simply an advertisement for your product or services) you can out it up there and see if anyone votes for it.
One idea I particularly like was Salesforce Marketing for Small Businesses, although I think it is something that deserves an entire track as opposed to a single session. I actually wrote a bit about just that after the last Dreamforce, part of my Five Things to Make Dreamforce Better post. Here's an excerpt:
"Create a new track: Guerilla Salesforce.com
-- Bigger does not necessarily mean more interesting. At the keynotes, at the awards, and in the breakout sessions the customer references and case studies are overwhelmingly dominated by big customers. I understand -- big customers are cool. But last time I checked, the vast majority of customers (heck, the vast majority of partners) all have less than 100 employees. I was in one marketing track where the speaker asked how many attendees worked in marketing departments with less than five people in them. Most of the room raised their hands. Here's what you do. Create a track dedicated to best practices and creative ways to use Salesforce.com without a lot of extra development, and without a single App off the AppExchange that you can't download for free....and create an Appy Award that a customer with less than 100 seats has a shot at winning. "Most Creative Use of Salesforce.com Without Spending a Penny."
