Why's that comical? If you have something interesting to say, go for it! Even if you don't, there's no harm in applying.
Most people are way more interesting than they think they are.
Based on my own experience, I'd say that you can always start out by speaking at local user groups or Meetups, build a resume of talks you've given, then apply to smaller / regional conferences, do a few of those, and ... well, that's where I stopped. All Things Open is the most prominent event I've presented at. But the point is, bootstrap and work your up the ladder.
Look at the whole thing holistically too: blogging, putting content on Youtube, open source projects, etc, all go towards building your overall image and presence "out there".
