yan: I just realized what'd make a great feature, in my opinion: Add a "recommend alternate" option. For instance, if I see a command I know is suboptimal or there exist other tools that do the job better, I can submit an alternate way to perform the same action.For instance, I see something like:  find $PWD -type f -exec grep pattern {} \;

I can suggest an alternate to be:  grep -r . pattern
