Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

The solution to a year long (and extremely frustrating) problem I've had, caused by the fact that I only have one speaker; this command downmixes the stream to monophonic output, making sure I don't miss any of the music.
NOTE: When stream is in .m3u format, a -playlist option is required, as shown below:
mplayer -af pan=1:0.5:0.5 -channels 1 -playlist radiostream.m3u
This command works great with aliases for various channels in .bashrc. Sample below:
alias radio1='mplayer -af pan=1:0.5:0.5 -channels 1 radio1stream.pls'
There are 9 alternatives - vote for the best!
