There are lots of people who don’t see any reason to use anything other than Google for search. That’s fine. But sometimes you want to search very specific things: Amazon for products, Wolfram Alpha for science and data answers, or the docs for your programming language of choice. From DuckDuckGo’s search bar, that means just two extra characters to customize your search: “!a flashlight” for that Amazon search, “!wa population of Cleveland OH” for Wolfram Alpha, and “!jquery arrays” for certain programmers.
Twitter and Facebook: Both Twitter and Facebook put a notable amount of effort into recreating their app experience on their mobile sites. They are good, if not perfect, interfaces. But you have an app for those services, right? On both iPhone and Android, in fact. But if you’ve ever sent a tweet from the wrong account, or waited for what seemed like an entire coffee break for Facebook’s app to catch up with itself, having the mobile bookmark handy is quite useful. I stay logged into Twitter from some of my side projects, so that Twitter’s app and its notifications don’t leave me tweeting about the wrong thing in the wrong channel.
Which mobile web apps do you find worth bookmarking in the age of the “store?”
