If you have a Pocket PC PDA or Windows Mobile Smartphone and use Wikipedia regularly, check out the Wikipedia in MDict Format.  Basically, this is a dump from the Wikipedia database to be viewed offline.  I personally don’t rely on Wikipedia as a primary source of information, but this looks like a handy reference tool to use in conjunction with other sources.

Google is branching out again.  This time, they have launched a competitor to Wikipedia.  Google has launched Google Knol.  Google opened the service to a “public beta” in July 2009 with a few hundred articles.  Since then, their database of articles has gradually grown.  Its hard to say whether this will be a Wikipedia-killer or not.  However, Google will supposedly be verifying that individual accounts are legitimate before allowing permission to create new articles.
