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.

I have found that base64 encoded webshells and the like contain lots of data but hardly any newlines due to the formatting of their payloads. Checking the "width" will not catch everything, but then again, this is a fuzzy problem that relies on broad generalizations and heuristics that are never going to be perfect.
What I have done is set an arbitrary threshold (200 for example) and compare the values that are produced by this script, only displaying those above the threshold. One webshell I tested this on scored 5000+ so I know it works for at least one piece of malware.
