There are so many alternative search engines in the market today. I came across a new alternative search engine that might be work bookmarking, ErrorKey. ErrorKey is a new search engine dedicated to provide results for any error you encounter. Developed in a way that it crawls across the web to search for information associated to various errors plus builds itself up from contribution by users and other developers alike, it just requires you to type in an error and get information about it. It also has pre-defined tags that contain search results associated to various devices, programs etc (HTTP to Cars). It’s neat and pretty useful if you are looking for errors alone.

Chacha is a mobile service that is trying to enter the competitive market of mobile search. Mobile search is currently thought of as an online product, so Google or Yahoo search for example, but mobile search can also mean that you get the answers without having to go online. How does that work? Well in the case of Chacha all you have to do is send them a text message with a question and they response seconds later with the answer.
Simply text your question to 242242™ (spells ‘ChaCha’) or call 1-800-2ChaCha™ (800-224-2242) from your mobile phone to ask any question and you will receive the answer as a text message. If you have a web browser on your phone, just click on the short website link that’s also included with your answer to see a reference website with more information. Since ChaCha uses human guides, you can easily reply with follow-on questions as if you are exchanging messages with a friend.
