commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

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,…):

Manpages, command summaries, and pretty much everything else usually have the information you're most likely to want at the beginning. Seeing just the last 40 or so lines of options from a command that has 100 is not super useful, and having to scroll up each time you want to glance at something is spastic.
Run this and then do something like
p do vi --help
and you'll get the first screen(-mostly-)full of vi's usage info and options list
to page down, and
to page up.
To see the current page again:
Also useful for situations like
p do aptitude search ~dsmorgasbord
#p sudo aptitude -r install libwickedawesome-perl-snoochieboochies
p sudo aptitude -r install libwickedawesome-perl-snoochieboochies snazztasticorama-dev-v0.∞
where you're using readline up-arrow, HOME, END, etc., to quickly recall commented commands.
For the unaware, that option to aptitude search will bring up all of the packages whose descriptions contain the string "smorgasbord". Depending on your distro, there could potentially be hundreds of them.
There are 10 alternatives - vote for the best!
