I’ve really been impressed with Yelp and the extent that they’ve been able to create an ecosystem where they can influence which restaurants and services that patrons go to. That’s pretty awesome. It puts the power in the hands of the consumer and forces the establishment to step up their game.
Tumblr also fascinates me. I know a lot of folks that use it as their full on blog. For me, its just a place to dump the random/interesting things that I find on the Web. Sometimes these are articles that I may want to blog about later and sometimes not. Tumblr just put out a iPhone app so I want to have some fun with that and document more of the randomness that is my life.
So yeah… do you guys use Yelp or Tumblr? Any new cool social networky type Web apps that I should be paying attention to?
