Wikis are great, because through an active community, it creates a lot of information on a topic, practically enough to fill encyclopedias. Users can freely create or edit information on each aspect of the subject, adding to a common body of knowledge.

star trek fans love looking through and adding to Memory Alpha because it helps them sort through the franchise's complicated background. I think the same will be true for users of smartphones and PDAs. As complicated devices with numerous features and issues, a definitive source of information is possible only through the collaborative efforts of many people. Unlike the hard-to-follow threads of a forum, a Wiki arranges information into easy-to-read articles. Below are three smartphone or PDA wikis I've found:

• HTC Wiki - Finally! A definitive (and probably up-to-date) list of HTC models and their aliases!


• Everything Treo - If you're a Treo owner and know a thing or two about the smartphone, help out this Wiki by contributing.


• Everything Q - It's interesting that one device alone can create a lot of content, such as Tips and Tricks.
