In short - it's a repository for unix/bash commands that you want to save for future use, featuring autocomplete search, voting and commenting (very much inspired by daily reading: HN, Programming Reddit, Stack Overflow ...). Kept as clean and simple as possible.
More: I really wrote this for myself as my own collection of command-line snippets was getting too unwieldy and hard to parse. I just wanted autocomplete really so I could jump straight to that command I can vaguely remember in a few characters.
We're quite hot on using Twitter at work for project communication (all SVN commits tweet) and commandlinefu lends itself nicely to tweet-sized nuggets. It turns out that it's quite a good way of staying in touch with the latest commands. All command lists are available as RSS feeds also.
It's still pretty raw at the moment - I've got a few features in the pipeline that should make it better such as tagging and requesting a needed command (see the uservoice link). However, it's gone onto reddit today so I thought now's as good a time as any to ask for HN feedback.
All feedback appreciated via this forum, or uservoice.
