Ask HN: Would you rather go to TED or Davos?

I'd have to say TED but that's only because I'm not familiar with Davos. Are you referring to the economic forum? In that case TED because of the variety of topics. I stand to be corrected of course.

Davos, just because of the people who are there. TED talks are like mind crack, it gives you a quick hit but fills your head with bad ideas.

You could also go to the BIL conference - http://www.bilconference.com

Thanks for this link. Bookmarked.

Are these conferences good place for startups to present their product and/or network with angel investors..etc..?

Davos every time. Look at the people who'll attend. The calibre is guaranteed to be higher.
