Boring endless presentations. This is what modern conferences are all about.
This trend needs to be stopped as soon as possible. As more people put their hands on Powerpoint/Keynote/Impress and so forth, more bullet pointLESS productions arise.
If you attend regular conferences and maybe you paid to participate I think that this is the ultimate masochistic practice you can experience on yourself.
On the other hand, if you attend unconferences you have a chance to set yourself free from boredom and control.
Just raise your hand and try to be as disruptive as possible. If the host tries to keep the concentration on his bullet pointLESS presentation just tell him that it's now time for discussion and that you already got the point.
It looks like we got to a point where barCamps and unconferences are now the most wanted stages for I-need-to-feed-my-ego type of speakers who have been rejected from regular conferences and now try to pitch their services in our beloved open settings.
Well if you attended a Camp recently or will in the future, I suggest you step up and stop the dictator of the session. You can also say that Julius from the EMBlog told you to.
You really need to get in another mindset when at unconferences or Camps. Speak up. Listen. Participate. Share. If you feel others are not doing that, just let the organizers know or tell the host because you don't realize that you've been thrown ten years back in the past.
Update: Well it looks like me and Seth Godin agreed this morning about bullet points... have a look at his latest post.
