I'm working on a tool that gives you access to things you do online in a really efficient manner. It works best with services that tie into a current webpage you are viewing. Yeah, it's a little hard to explain.
I'm curious to know which services you guys use. Here's what I have so far:
* To find website popularity: Quantcast, Alexa, QuirkBase, Compete
* Technicals about a website: Domain Tools, BuiltWith, WebPageAnalyzer
* Backtype - find discussions on reddit, digg, etc, pertaining to a URL
* UrbanDictionary - find out what various TLAs mean and such
* Google, Google Maps, Google Translate
* Wikipedia
* Delicious (to find similar web pages)
* TinEye (to find where else photos appear)
* Imgur
