Since TikiWiki is a community and not just a software, more social aspects than just hacking on our favourite code are considered. One of them is the TikiWiki last.fm group, where you can get an impression of the average TikiWiki-user's musical taste or even change it to become more like yours.
Last.fm is an AudioScrobbler compatible community site, which allows users to get recommendations on music they might be interested in. By submitting the titles of what you hear, the last.fm server is able to data-mine personal recommendations for you by comparing you to users who hear the same music - amazon-style, only you don't have to buy!
TikiWiki's use of this great system started with the initiative of luci to open up a TikiWiki Group in last.fm's "Websites" category. After announcing it on IRC some users hopped on board immediately and have influenced TikiWiki's musical taste for about a month now.
Do you really want to leave the control over Tiki's taste in the hands of just some geeks...?
