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,…):

If you are downloading a big file (or even a small one) and the connection breaks or times out, use this command in order to RESUME the download where it failed, instead of having to start downloading from the beginning. This is a real win for downloading debian ISO images over a buggy DSL modem.

Shows a list of running virtual machines on a vmware host (workstation/server/esx/etc.)
Again, this command is vmware-specific.
There are also other things you can do with `vmrun`. Just simply type vmrun by itself (no arguments) to get a readout of other things you can do with it.
There is no output from this command. The command boots a virtual machine and you will have to wait for the boot sequence to complete before you can ping or connect to the virtual machine via ssh/rdp/vnc/nx/etc.
Performs a mysqldump and gzip-compresses the output file with a timestamp in the resulting dump file. Inspect the file for integrity or fun with this command afterward, if you desire:
zcat mysqldump-2009-06-12-07.41.01.tgz | less
