Yes, but ALWAYS put a BIG warning before sending normal users to Extras-Devel or Extras-Testing. Installing unstable software can create a very bad first impression for new users of Maemo / Linux / Open Source.
Please see http://talk.maemo.org/showthread.php?p=343619 .

For people interested in testing (turn your device into a brick, lose all your data, and have lots of fun while doing that) see http://wiki.maemo.org/Extras-testing .
